Question

find the cost of tilling courtyard 30 m long and 15 m broad at rate of rs 5 per sq CM

Answer 1

here is your answer

given length = 30 m and breadth = 15 m

finding area --

area = l x b = 30 x 15 = 450 sq metres

converting into sq cm --

1 sq m = 10,000 sq cm

450 sq m = 450x10,000 = 45,00,000 sq cm

finding the cost --

given 1 sq cm = Rs 5

45,00,000 sq cm = 45,00,000 x 5 = 2,25,00,000.

hence cost of courtyard is 2,25,00,000.

hope it helps you .
