Question

a swimming pool is 15 m in length 12 metre in breadth 2 metre in depth find the cost of cementing the floor and walls @ rupees 15 per square metre

Answer 1

Given,

L= 15 m

b= 12 m

h= 2 m

First we find the area of floor = 15 × 12

= 180 m²

Then, we find area of walls

= 2(15x2) + 2(12x2)

= 2(30 + 48)

= 156 m²

Add both to get total area

= 180+ 156 = 336 m²

Multiply total area and cost per m²

= 336 x 15

= ₹5,040
