Question

A tile has a shape of a parallelogram whose base is 28cm and the corresponding height is 20cm.How many tiles are required to cover a floor of area 2800m²?

Answer 1

Step-by-step explanation:

Given that

Base is 28cm

Height is 20cm

Area of floor is 2100 sq mtr

To find number of tiles

Solution

$area \: of \: parallelogram \: tiles = 28 \times 20 \\ 560c {m}^{2}$

$floor \: area = 2800 {m}^{2}$

$floor \: area = 2800 \times 100 \times 100 \\ = 28000000c {m}^{2}$

$number \: of \: tiles = \frac{floor \: area}{area \: of \: parallelogram \: tiles} \\ \frac{28000000}{560}$

hence numbers of tiles will require is 50000.
