Answer:
The answer is 8 ft
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
perimeter = 40 ft
length = 12 ft
Substitute the values into the above formula and solve for the width
That's
40 = 2(12) + 2w
40 = 24 + 2w
2w = 40 - 24
2w = 16
Divide both sides by 2
We have the final answer as
8 ft
