Question

The area of a rectangular field of length 16m and breadth 9m is equal to the area of a square. Find the perimeter of a square and the cost of fencing it at rs 15 per m the cost of planting grass on the rectangular field at the rate of rs 80 per sq m​

Answer 1

Answer:

Area of rectangular field = L×B =16×9= 144

Given Area of sqaure =area of rectangle

therefore area 8f sqaure=144 =side ×side= 12 ×12

perimeter of sqaure =12 ×4 = 48

cost of fencing of sqaure =48×15=720

cost of planting grass = 144 ×80 =11520

Answer 2

Answer:

Length- 16m

Breadth - 9m

Area of rectanglular field - L multiply b - 16 multiply 9 - 144m

so the area of rectanglular field is equal to area of square - 144m

Area of square - side multiply side

144m - x multiply x

x (2) - 144m

x- 144/2

x- 72m

so one side of square is equal to 72m

perimeter of square- 72 multiply 4

perimeter of square - 288m

Step-by-step explanation:

Now you can find cost by yourself
