given,
ratio=5:12:13
perimeter=300cm
5x+12x+13x=300
30x=300
x=300/30
x=10
lengths are 50cm,120cm,130cm.
area=√s(s-a)(s-b)(s-c)
=√150(150-50)(150-120)(150-130)
=√150(100)(30)(20)
=√9000000
=300cm²
we know that,
area of triangle = half of the base of the height
300= 1/2 ×130× height
300=1/2 ×130× height
300×2/130= height
height=4.61cm
MAYBE IT IS USEFUL TO U . ONCE CHECK THE ANSWER IS IT CORRECT OR WRONG. I DONT KNOW THE ANSWER.
