Question

A rectangular courtyard, 18 m 72 cm long and 13 m 20 cm broad is to be paved with square stones of the same size. find the least possible number of such stons.

Answer 1

Hello!

For the total pavement, we have to find the area of the rectangular field.

Length = 18.72 m

Breadth = 13.20 m

Area = length x breadth

= 18.72 x 13.20

= 247. 104 m

For the area of one square stone, we have to under- root the area of rectangle because the area of square is (side)².

= 15. 71 m (approx)

Therefore, the area of 1 square stone = 15. 71 m.

Total stones required = Area of rectangle/ Area of square

= 247. 104 / 15. 71

= 15. 72 (approximately = 16)

Therefore, minimum stones required = 16



I hope it helped.

Thank You
