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 and width of the rectangle

Answer 1

Answer:

w-6    l-12

Step-by-step explanation:

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.
