Question

in the given square, find the area of shaded region

Answer 1

Step-by-step explanation:

Given: a = 3 cm

b = 4 cm

c = 5 cm

To find: Area of shaded region, i.e. triangle.

Soln: Semi-perimeter (s) = a+b+c/2

= 3+4+5/2

= 12/2

•°• s = 6 cm

•°• Area of the triangle = √s(s-a)(s-b)(s-c)

= √6(6-5)(6-4)(6-3)

= √6 × 1 × 2 × 3

= √36

= 6 cm²

•°• Area of the shaded region (triangle) is 6 cm².
