Question

cost of flooring a square room whose each side is 8 cm at the rate of 21 rupees​

Answer 1

answer-

each side of square room = 8 cm [ i think it should be in metres, but in question it is given in cm so i am solving in cm]

area of floor = area of square

we know, area of square = side*side

so, area of floor = 8cm * 8cm

area of floor = 64 cm²

cost of 1 cm² = rs. 21

so, cost of 64 cm² = rs. 21 * 64

cost of 64 cm² = rs. 1344

cost of flooring the square room = rs. 1344

hope it helps

have a nice day
