What is the area and perimeter of a rectangle?

The perimeter P of a rectangle is given by the formula, P=2l+2w , where l is the length and w is the width of the rectangle. The area A of a rectangle is given by the formula, A=lw , where l is the length and w is the width.

What is the area of the rectangle?

In other words, the area of a rectangle is the product of its length and width. That is, A = l x w where l is the length and w is the width of the rectangle. For example, the area of a rectangle of length 35 m and width 25 m is 35 times 25 or 875 square meters.

How do we find the perimeter of a rectangle?

The perimeter of a rectangle is the total length of all the sides of the rectangle. Hence, we can find the perimeter by adding all four sides of a rectangle. Perimeter of the given rectangle is a + b + a + b.

How do you find the area in the perimeter of each of a rectangle?

Video quote: Finding the perimeter of a rectangle. Three strategies you can use. The perimeter is the distance all the way around the outside of something the lines that make up this rectangle. Are the perimeter.

What is perimeter and area?

Firstly, the area of a shape is the surface or flat space that the shape covers whereas the perimeter of a shape represents the distance around its boundary. Secondly, the area is measured in square units, whereas the perimeter is measured in linear units.

How do you calculate a perimeter?

Video quote: So the answer is 84 square centimeters to find the perimeter member the perimeter is just adding all the sides. So if you see here a rectangle has one two three four sides.

How do you find the perimeter with the area?

What is its area? Divide the perimeter by 4: that gives you the length of one side. Then square that length: that gives you the area.

What is the unit of perimeter of rectangle?

What are the Units of Perimeter of a Rectangle? The perimeter of a rectangle is measured in linear units, like meters, centimeters, inches, or yards. The perimeter is equal to the boundary of the rectangle which can be calculated with the formula: Perimeter = Length + Length + Width + Width = 2(Length + Width).

What is room perimeter?

The perimeter P is the total length around the room. A is the area of the room.

How do you find area?

The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

What is area formula?

Area = length × length.

What is the perimeter of my house?

Add together the lengths of all the walls to calculate the perimeter of any room. For example, suppose a room has two curved walls that measure 18 and 20 feet, and three straight walls that measure 18, 24, and 15 feet. Adding those numbers together results in a perimeter of 95 feet.

What units do you use for area?

In the International System of Units (SI), the standard unit of area is the square metre (written as m²), which is the area of a square whose sides are one metre long. A shape with an area of three square metres would have the same area as three such squares.

What is the area and perimeter of a square?

Area of a Square = side × side = side² square units



where “s” is the length of one side. Hence, the perimeter of square will be: Perimeter = 4 x side = 4 √Area units.

What is the area of a 12cm square?

Thus, the area of the square is 144 cm².

What is the area and perimeter of square and rectangle?

The perimeter of a rectangle is P=2b+2h, where b is the base (or width) and h is the height (or length). If a rectangle is a square, with sides of length s, the formula for perimeter is Psquare=2s+2s=4s and the formula for area is Asquare=s⋅s=s2.
