Answer:
Length = 12 meters
Step-by-step explanation:
Rectangle
Perimeter P = 2(L + W)
The length of a rectangle, I, is six meters more than it's width, W.
Then L = W + 6
So
P = 2(W + 6 + W)
P = 2 (2W + 6)
P = 4W + 12
Plug in P = 36 meters
36 = 4W + 12
4W = 36 - 12
4W = 24
W = 6 meters
L = 6 + 6
L = 12 meters
d
1. 6 (3)^2 = 54 ft ^2
2. 6 (2)^2 = 24 ft ^2
3. 54+ 24 = 78 ft^2
The student made an error during the distributive property in the second step where they multiplied 0.15 by -0.2 to equal -0.3 when it should have been -0.03.
