A livestock pen is built in the shape of a rectangle that is four times as long as is wide. The total perimeter is 60 ft. Write

bonufazy [111]

Answer:

Perimeter = 60ft = 2(4x + x)

breadth = 6ft

length = 24ft

Step-by-step explanation:

Perimeter = 2 (L + B)

L =length

B = Breadth

x= breadth

4x = length

Perimeter = 60ft = 2(4x + x)

Dividing both sides by 2 :

30ft= 4x + x

30ft = 5x

divide both sides by 5

6ft= x

breadth = 6ft

length = 4x= 4 x 6 = 24ft
