The diagram shows a rectangular garden path. 120 cm
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

Yes he has enough money to buy all and he is left with $20 at last.

Step-by-step explanation:

area=120×600=72000

area of square marbles=30×30=900

number of marbles needed to cover the garden=72000÷900=80

cost of each marble =$2.50

cost of 80 marbles =80×$2.50=$200
