Answer: width = 72.50 m

Step-by-step explanation:

P = 2l + 2w

425 = 2( 140 ) + 2w

425 - 280 = 2w

145 = 2w

w = 72.50

Answer:

The width of the field is 72.5 m

Step-by-step explanation:

The field is rectangular in shape

The length of the field (L) = 140 m

The perimeter of the field (P) = 425 m

The width of the field (W) is unknown

P = 2L + 2W

425 = 2(140) + 2W

425 = 280 + 2W

425 - 280 = 2W

145 = 2W

W = 145/2 = 72.5 m
