Question

18 The diagram shows a rectangular garden path. 600 cm Wasim is going to cover the path with paving stones. Each paving stone is a square of side 30 cm. Each paving stone costs £2.50 Wasim has £220 to spend on paving stones. Show that he has enough money to buy all the paving stones he needs. 120 cm​

Answer 1

Explanation:

A = 600 x 120 = 72 000 cm^2

Area of a paving stone = 30^2 = 900 cm^2

number of paving stone = 72 000 : 900 = 720 : 9 = 80

Total cost = 2.50 * 80 = £200.00
