th of the rectangle
1 answer:
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.
