Chapter 8.6, Problem 61CCR

To determine

Find the area of the figure.

Answer to Problem 61CCR

Area of Triangle ABC is 63 sq cm

Explanation of Solution

Given:

The figure: Height = AD = 7 cm and Base = BC = 18 cm

  

Concept Used:

Triangle ABC is a Triangle.

Rule: $\text{Area}\text{of}\text{Triangle}=\frac{1}{2}·\text{base}·\text{height}\text{.}$

Calculation:

Dimensions of ABC: Height = AD = 7 m and Base = BC = 18 cm

  $\text{Area}\text{of}\text{Triangle}=\frac{1}{2}·\text{base}·\text{height}\text{.}$

  $\text{Area}\text{of}\text{Triangle}\text{ABC}=\frac{1}{2}·\text{18}·\text{7= 63 sq cm }$

Thus, Area of Triangle ABC is 63 sq cm
