A rectangular animal pen will be built using 200 meters of fencing. If one side of the rectangle is 60 meters, find the area of the pen. 1200 m^2 1400 m^2 2400 m^2 8400 m^2

Solution

Dear student

Thank you for using chegg !!

Let the length of rectangle be l Meters and breadth be b Meters

Perimeter = 2(l +b)

Given l=60 Meters

Perimeter = 200 Meters

Substituting

200 = 2(60 + b)

b= 40 Meters

Area of reactangle = l X b

= 60 X 40

= 2400 meter^2
