Answer 1

$135

Explanation:

15-12=3/2=1.5

12+1.5=13.5

13.5*10=135

Answer 2

$1620

Explanation:

The area of the lawn is a trapezoid.

Area of a trapezoid =
`\frac12(a+b)h`

where a and b are the parallel sides (bases) and h is the height

Therefore,

`area=\frac12(15+12) * 10 = 135 \ m^2`

If the price of sod is $12 per square metre, then

total cost = 135 x 12 = $1620
