Question

How many pieces of stone slabs, each 26cm long and 10 cm broad will be required to lay a path of 260 m long and 15 m wide? ( with solutions)​

Answer 1

For each slab,

length = 26 cm, breadth = 10 cm

From the given dimensions we can see that each slab is in the shape of a rectangle.

Therefore, the area of a slab = length × breadth

= 26 cm × 10 cm

= 260 cm2

For the path,

length = 260 m, breadth = 15 m

Therefore, the area of the path

= (260 × 15) m2

= 260 × 15 × 10000 cm2

[

∵

1 m2 = 10000 cm2]

Therefore, number of slabs required
