Chapter 11, Problem 11PT

To determine

To calculate the area of the trapezoid.

Answer to Problem 11PT

  $50.1$ square centimeters.

Explanation of Solution

Given information:

In the trapezoid, bases are $a=6.4$ centimeters and $b=10.3$ centimeters while height $h=6$ centimeters.

Formula used:

Area of the trapezoid $t=\frac{a+b}{2}\times h$

Where ‘a’ and ‘b’ are the parallel bases and ‘h’ is the height.

Calculation:

Area of the trapezoid.

  $t=\frac{a+b}{2}\times h$

Formula to compute the area of a trapezoid.

  $=\frac{6.4+10.3}{2}\times 6$

Putting the values in the formula.

  $=16.7\times 3$

Multiplying the same.

  $=50.1$ square centimeters.
