Question

Find the cost of painting a compound wall which is 100m long and 7m high at ₹ 15 per sq m

Answer 1

Heya!!

okay, so the length if the wall is 100m and the height of the wall is 7m .
Thus, the area of the wall will be
$100 \times 7 = 100 {m}^{2}$
The cost of painting is ₹15 per square metres.
so, the total cost of painting 700m^2 area will be
$700 \times 15 = 10500 \: rupees$
Thus, there will be an expenditure of ₹10500 for painting that wall

Hope, the answer was helpful

Answer 2

Area of the wall = 100*7

= 700m sq

Cost per m sq = Rs. 15

Cost for 700 m sq = 15*700

= Rs. 10500
