Question

The rectangle piece of land is 400 m × 150 m. find the cost of this piece of land if 1 spyware meter of land cost 15000 Ruppes. ​

Answer 1

Step-by-step explanation:

Ratio of length to bradth = 5:3

So, let length = 5x and breadth = 3x.

Cost of fencing = Rs. 7 per m

Total cost = Rs. 2800

Therefore, perimeter = 400 m

2(5x+3x)=400

8x=200

x=25

So, length = 125 m

Breadth = 75 m

Area = 125×75=9375 m
