Given:
Volume of trailer space = 180 cubic ft
Height of trailer, h = 7.5 ft
Width of trailer, w = 4 ft
Perimeter of base of the trailer, P = 20 ft
Let's find the dimensions of the trailer.
Apply the perimeter of a rectangle formula:
P = 2L + 2W
Input values into the formula:
20 = 2L + 2(4)
20 = 2L + 8
Subtract 8 from both sides:
20 - 8 = 2L + 8 - 8
12 = 2L
Divide both sides by 2:
The length of the trailer is 6 ft
The width of the trailer is 4 ft (the width was given)
ANSWER:
Length of the trailer = 6 ft
Width of the trailer = 4 ft
