Question

A courtyard 18 m long and 14 m wide is to be paved
with bricks of length 25 breadth 13 cm. Number of
bricks-
​

Answer 1

Answer:

Length of court yard = 20m

breadth = 15 m

area = l×b = 20×15 = 300m² = 300×10000 cm²

length of a brick = 25cm

breadth = 12cm

area of a brick = 25×12 = 300 cm²

number of bricks = (area of courtyard)/(area of a brick)

= (300×10000)/(300)

= 10000 bricks
