Question

A rectangular field has a length of 105 m. The perimeter of the field is 408 m. What is the width of the field in meters? A) 250 m B) 100 m C) 125 m D) 99 m

Answer 1

D

Explanation:

the perimeter (P ) of a rectangle is calculated as

P = 2( length + width)

given P = 408 m and length = 105

substitute these values into the formula for P

408 = 2( 105 + width) ← divide both sides by 2

204 = 105 + width ( subtract 105 from both sides )

99 = width

that is the width is 99 m
