Question 42

Rectangular wall MNOP of a kitchen is covered with square tiles of 15 cm length (as shown in the figure). Find the area of hte wall.

Answer 1

In rectangular wall MNOP,

Number of square tiles = 28

Length of one square tile = 15 cm

In square, all sides are equal

$\therefore$ Area of one square tile = Side $\times$Side= 15 $\times$15 = 225 $c{m}^2$

$\therefore$ Area of 28 tiles = 225$\times$28 = 6300 sq cm

Hence, total area of wall MNOP is 6300 sq cm.
