Answer this question
A rectangular plot is 75m long and 35m wide. Find cost of levelling the plot at the rate of rupees 5 per square metre

2. The area of a square field is 225 sq.m. Find the cost of fencing it with wire at rupees 21.50 per metre

Answer 1

Question 1 :

Area of the rectangle = l x b

= 75 x 35 = 2625m²

Rate = Rs. 5 / m²

Rate of levelling the plot = 2625 x 5

= Rs. 13,125

Question 2:

Area=(Side)²  

(side)²=225 m²

side=√(225)  

side=15 m

perimeter=4*side  

perimeter=4*15 m  

perimeter=60 m  

cost of fencing=60*21.50  

cost of fencing= 1290 rupees
