Find the dimensions of the original rectangle.

Question

A rectangle has a length 4 m less than twice its width. When 3 m are added to the​ width, the resulting figure is a square with an area of 100m^2. Find the dimensions of the original rectangle.

Answer 1

Draw and label a diagram!

Original rectangle is (2w - 4) by w

The square is (2w - 4) by (w + 3)

Sides are equal,

2w - 4 = w + 3

Can you solve for w and answer?
