Question

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

In rectangular wall MNOP,

Number of square tiles = 28 Length of one square tile = 15 cm in square, all sides are equal

∴ Area of one square tile = Side × Side

= 15 × 15

= 225 cm²

Area of 28 tiles = 225 × 28 = 6300 sq cm

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