Question

how many blocks is 25 cm long and 12 cm wide will be required to lay a path 12.5 metre long and 4.8 metre wide​

Answer 1

Step-by-step explanation:

Area of block = 25*12=300cm sq.

Area of path =12.5m=1250cm

4.8=480cm

1250*480=600000cm sq.

No. Of blocks =600000÷300=

2000 blocks

$\large \blue{{★Question★}}$

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

$\large \pink{{★solution ★}}$

Length of the path = 12.5 m = (12.5 × 100)cm = 1250 cm

Width of the path = 4.8m = (4.8 × 100)cm = 480cm

▪︎ Area of the path = (1250 × 480)cm² = 600000 cm²

Length of each block = 25 cm

Width of each block = 12 cm

▪︎Area of each block = ( 25 × 12) cm² = 300 cm²

▪︎No. of block required = 600000\300 = 2000
