cost
of cementing its floor and walls at Rs. 15 per m²
​

Answer 1

Answer:

Area of floor= 750m^2

Cost of cementing the floor = 750×15=₹11250

Step-by-step explanation:

Answer 2

Step-by-step explanation:

swimming pool shape = rectangular

(cuboidal)

length=30m

breath=25m

depth or height = 8m

so we need to find the cost of cementing its floor only so we dont have to use height.

floor= rectangle 2d figure

area = l×b

area =30×25

area = 750m2

$750m^{2}$

now cost = area × rate

area = 750

rate=15m per square

750×15

= 11250

hence cost of cementing the floor is ₹11250
