Given :

There is a slide in a park. One of its side walls has been painted in some colour

The sides of the wall are 11m, 15m and 6m.

To Find :

  • 1.The semi perimeter of the triangle

  • 2.Area of the triangle is

  • 3.Formula to find perimeter of the triangle

  • 4.Formula to find area of the sidewall

  • 5.Perimeter of the triangle

Solution:

s = (a + b + c)/2

a = 11

b = 15

c = 6

The semi perimeter of the triangle s = (11 + 15 + 6)/2

= ( 32)/2

= 16 m

Formula to find area of the sidewall is

Heron formula = √s(s - a)(s - b)(s - c)

Area of the triangle = √16(16 - 11)(16 - 15)(16 - 6)

= √16(5)(1)(10)

= 20√2 m²

perimeter of the triangle = a + b + c

= 11 + 15 + 6

= 32 m
