Question

1. How many blocks, each 25 cm long and 12 cm wide, will be required to
lay a path 12.5 m long and 4.8 m wide?
​

Answer 1

Answer:

20 blocks

Explanation:

length of block = 25cm

width of block = 12cm

so, l×b = 25×12 = 300cm

length of path = 12.5

witdth of path = 4.8m

so, l×b = 12.5×4.8 = 60m

1m = 100cm

60m = 60×100 = 6000cm

so, 6000/300 = 20

so, 20 blocks are required.
