What is a rectangle model?

In mathematics, an area model is a rectangular diagram or model used for multiplication and division problems, in which the factors or the quotient and divisor define the length and width of the rectangle.

What are rectangular models?

The rectangular fraction model means a rectangle divided into equal parts. The equal parts may be halves, thirds, fourths, and so on, depending on how many equal parts you chop the whole into. Remember that in any fraction, the number on the top is the numerator, and the number on the bottom is the denominator.

What is area multiplication?

The Area Model: What We Typically See



The area of the rectangle will be our product. We decompose the factors into tens and ones. Then we multiply the parts to find the product for each part of our rectangle. In this example, we multiplied 10×10 to make 100, 10×3 to make 30, 2×10 to make 20, and 2×3 to make 6.

What is 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.
