Question

answer this question above me with explanation

Answer 1

sides ratio 5:12:13

and peramiter of triangle = 150

then
sum of the sides = perimeter
(5*x)+(12*x)+(13*x)=150
30x=150
x=5

then
sides of this triangle = 25, 60, 65

Area of triangle = A = root(s*(s-a)*(s-b)*(s-c))

where S = (a+b+c)/2=(25+60+65)/2=75

then

A = root (75*(75-25)*(75-60)*(75-65))
= root(75*50*15*10)
=root(562500)
= 750cmsq

area of triangle = "750cmsq"

I hope it will help you...
