Answer to Problem 31SGR

  $\$76.245$

Explanation of Solution

Given Information: Trapezium and $2.99 per square foot.

Formula Used:Area of Trapezium= $\frac{1}{2}\times Base\times Height$

Calculation:

Area of Trapezium: $\frac{1}{2}\times Sumofparallelsides\times Height$

Now, parallel sides is of 6ft & 11ft and height is of 3 ft.

Area of Trapezium: $\frac{1}{2}\times (6+11)\times 3squarefoot$

Area of Trapezium: $\frac{1}{2}\times 17\times 3squarefoot$

Area of Trapezium: $25.5squarefoot$

Cost of 1 square foot = $\$2.99$

Cost of 25.5 square foot = $\$2.99\times 25.5$

Cost of 25.5 square foot = $\$76.245$
