Answer:
A = 200ft²
Info:
l = 2w
P=2[(2w)+w)
P = 60
A=w(2w)
Step-by-step explanation:
Since we know the value of the perimeter, it's actually easy to solve with the information listed above.
Firstly, since the equation has the same variable, you can actually add them or multiply. You can write the perimeter in a new way,
P=6w
which means w = [tex]\frac{p}{6}[/tex], [tex]\frac{60}{6}[/tex] or 10ft.
Now we know the width you can get the length by multiplying it by 2. Let's get the rectangle area.
A=w(2w) or A=wl
A=10(2x10) or A=10(20)
A = 200ft²
