Answer 1

Answer:

£125

Step-by-step explanation:

First, find perimeter.

630 + 630 + 120 + 120 = 1500

Divide by stone width.

1500 / 30 = 50

Multiply by the cost.

50 x 2.5 = 125

Answer 2

2520 stones which will cost £6300

Step-by-step explanation:

First find area of path:

630 x 120 = 75600 cm²

then find how many stones will be needed:

75600/30 = 2520

then find out the total cost:

2520 x 2.5 = £6300
