Question

the length of a ractangle is 1 meter less than its width. the area of the rectangle is 42 square meters. Find the dimensions of the rectangle (using the x method)

Answer 1

Length : 6
Width : 7

Explanation:

I'm not 100% sure what this x method is but it should be something like this:

A = L × W

42 = L × W

W = L + 1

L = W - 1

If we substitute L with 7 and 6 with W it will satisfy the above equations:

42 = 6 × 7
