Answers
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
