Question

Find the area of the shaded part of the figure if a = 7, b = 10, c = 3

Answer 1

Answer:

65

Step-by-step explanation:

First lets find the area of the bottom rectangle

area of the rectangle = length × breadth

                                   = 10 × 3

                                   = 30

now lets find the area of the the above triangle

area of triangle = $\frac{1}{2}$ × base × height

                          =  $\frac{1}{2}$ × 10 × 7

                          =  $\frac{1}{2}$ × 70

                          = 35

now add area of rectangle + area of tringle

= 30 +35

= 65
