Question

The area of rectangular plot is 432 m square.if its length is 18 M find its perimeter also find the cost of the financing it at 5rupees per metrer?

Answer 1

Answer :-

Perimeter = 144m

Cost of fencing it = Rs 720

Step - by - step explanation :-

Area of the rectangular plot = 432m^2

Length = 18m

Breadth = ?

Area = length × breadth

432 = 18 × b

b = 432/18

b = 24m

Perimeter of the rectangular plot = 2 (length + breadth)

Perimeter = 2 (18 + 24)

= 2 × 42

= 84m

Cost of fencing it per meter = Rs 5

Cost of fencing 84m = 84 × 5

= Rs 420
