Question

9 A rectangle and a square have the same area. The length

of the rectangle is 70 feet more than two times its width. The
length of a side of the square is 30 feet. Set up an equation to
find the dimensions of the rectangle. What are the dimensions
of the rectangle? Include units of measurement.

Answer 1

Step-by-step explanation: If the square is 30 ft on one side the other side must be too. So 30x30 = 900. Now, we know the rectangle must also be 900 in area. So, the width must be 10feet and the length must be 90ft because 10x90 is also 900. How I got the length? I did 10x2+70.
