Question

The perimeter of a rectangular Park is 200 metre if its breadth is 35 M then find its length also find the cost of growing grass at Rs 12.5 m square

Answer 1

hey there

here is your answer

it is given that,

perimeter of a rectangular park = 200m

breadth = 35m

we know that : PERIMETER OF A RECTANGLE = 2 ( l + b )

2 ( 35 + l ) = 200   ( transposing 2 from left to right )

35 + l = 100

l = 100 - 35

l = 65m

area of a rectangle = l × b

65 × 35 = 2275m²

cost of growing grass at Rs 12.5 per m²

=> total cost = 12.5 × 2275

= Rs 28437.5
