Question

A verandah 50m long and 6m wide has to be paved with tiles, each
measuring 60cm by 50cm. Find the number of tiles needed.

Answer 1

1000 tiles.

Step-by-step explanation:

Length of verandah = 50m

Breadth of verandah = 6m

Area of verandah = l × b = 50 × 6 = 300m

Length of one tile = 60cm = 0.6 m

Breadth of one tile = 50cm = 0.5 m

Area of one tile = 0.6 × 0.5 = 0.30 m

Number of tiles needed = 300/0.30 = 1000

Answer 2

Given:

The length of verandah = $50$ m

The width of verandah = $6$ m

The length of each tile = $60$ cm

The breadth of each tile = $50$ cm

To find:

The number of tiles required

Step-by-step explanation:

Let us find the area of the verandah and each tile.

Area of verandah = Length $\times$ Breadth

Area of verandah = $50$ m $\times$  $6$ m

⇒ Area of verandah = $300$ m

Area of each tile =  $0.6$ m $\times$ $0.5$ m

⇒ Area of each tile =  $0.3$ m

$Number\;of\;tiles\;required\;=\;\frac{Area\;of\;verandah}{Area\;of\;each\;tile}$

$Number\;of\;tiles\;required\;=\;\frac{300\;}{0.3\;}\;=\;1000$

Answer:

The number of tiles needed is $1000$
