calculate the area of the shaded region in☝️

(its urgent)(use herons formula)

## Answers

**Answer:**

1074 m²

**Step-by-step explanation:**

First we need to find the area of the larger triangle.

Given, sides of larger triangle(a, b, c) are 120 m, 122 m, 22 m

Semi-perimeter = (120+122+22)/2

= 264/2

= 132 m//

According to Heron's Formula:

(pair the like numbers and take out of square root)

= 3 x 2 x 11 x 2 x 2 x 5

__= 1320 m²// __

Now we need to find the area of the smaller triangle

Given, sides of the smaller triangle (a, b, c) are 26 m, 24 m, 22 m

Semi-perimeter = (26+24+22)/2

= 72/2

= 36 m//

Apply heron's formula and find area

Area of shaded figure = area of larger triangle - area of smaller triangle

= 1320 - 24√105

approx. value of √105 = 10.25

area = 1320 - 24(10.25)

**= 1074 m²//**
