Question

solve it..........................

Answer 1

Perimeter of the triangle = 288m
Ratio of its sides = 3:4:5
3x + 4x +5x = 288m
12x = 288m
x = 24m
3x = 3*24 = 72m
4x = 4*24 = 96m
5x = 5*24 = 120m
Area of the triangle = square root of s(s-a)(s-b)(s-c)
s = 288/2 = 144m
Area = square root of 144(144-72)(144-96)(144-120)
= square root of 144*72*48*24
= square root of 2*2*2*2*3*3*2*2*2*3*3*2*2*2*2*3*2*2*2*3
= 2*2*3*2*2*3*2*2*3*2
= 3456m2
