Chapter 12.4, Problem 35CCR

To determine

To find: Total area of composite figure

Answer to Problem 35CCR

  $\text{56}{\text{.05cm}}^{\text{2}}$

Explanation of Solution

Given:

We know that

  $\text{Base of triangle=9}\text{.5cm,height of triangle=3}\text{.8cm}$

Formula:

  $\text{Area of triangle=}\frac{\text{1}}{\text{2}}\text{×b×h,Area of parallelogram=b×h}$

Calculation:

  $\begin{array}{l}{\text{area=(area)}}_{\text{1}}{\text{+(area)}}_{\text{2}}\\ \text{=}\frac{\text{1}}{\text{2}}\text{×9}\text{.5×3}\text{.8+4×9}\text{.5}\\ \text{=56}{\text{.05cm}}^{\text{2}}\end{array}$
