Question

A rectangle has an area of 0.24 of a square meter. What are some possibilities for the length and width of the rectangle? Tell why. Solve this problem anyway you choose.

Answer 1

Since you have wL/4 rectangle; that = a square/4; the measure of a square = 2(w+L)=perimeter; (w+L)^2=area.

Answer 2

Hi Wewe. If you recall, the area of a rectangle is defined as area = length x width, or A = L x W.

In this case, we know the area is 0.24 of a square meter, so we plug that value in for A in the equation. Now we have:

0.24 = L x W

To solve this equation, think about what factors 0.24 has. 24 has factors of 1, 2, 3, 4, 6, 8, 12, and 24. The factors of 0.24 will therefore have these digits. Dividing each factor of 24 by 10 gives us .1, .2, .3, .4, .6, .8, 1.2, and 2.4, which are all factors of 0.24.

Therefore, some possibilities for the dimensions of the rectangle with an area of 0.24 square meters are:

0.1 m x 2.4 m

0.2 m x 1.2 m

and so on
