Chapter 12.1, Problem 50SR

To determine

To calculate : To find the perimeter and area of given triangle.

Answer to Problem 50SR

The required perimeter of triangle is 18 m and area of triangle is $54{\text{m}}^2$ .

Explanation of Solution

Given information : Consider the given figure below:

  

Formula used : Area and perimeter of rectangle can be defined as,

  $\begin{array}{l}P=a+b+c\\ A=\frac{bh}{2}\end{array}$

Calculation : The required perimeter of triangle is,

  $\begin{array}{l}P=12+15+9\\ P=36\text{m}\end{array}$

The required area of triangle is,

  $\begin{array}{l}A=\frac{9\cdot 12}{2}\\ A=54m^2\end{array}$

Therefore,
