Question

The width of a rectangle is half as long as the length. the rectangle has an area of 72 square feet. what are the length of width of the rectangle?

Answer 1

Hello!

Let's put this into a system of equations.

w=0.5L
wL=72

Let's plug in the w value in the second equation.

0.5L(L)=72
L²=144
L=12

Now we plug our L value into the first equation.

w=1/2(12)
w=6

The width is 6 and the length is 12.

I hope this helps!
