Answer:a and b
Step-by-step explanation:
Width = x cm
Length = 4x - 16
Perimeter = x + x + 4x -16 + 4x - 16
28 = 10x -32
(+ 32 to both sides)
60 = 10x
6 = x
Width = 6cm
Length = (6x4) - 16
= 8cm

Answer:
W = field width = 48 ft
Step-by-step explanation:
Review: the formula for Perimeter of a rectangle is P = 2W + 2L.
Here we're told that the Perimeter is 168 ft. Therefore:
168 ft = 2L + 2W. But we are also told that W = 36 ft. Then:
168 ft = 2L + 2(36 ft) = 2L + 72 ft.
Subtracting 72 ft from both sides, we get 2L = 96, which tells us that:
L = 48 ft.
The field is 48 ft long.
