Question

Sides ratio of triangle are 8 :15:17 and its area is 1500 cm then find the perimeter of triangle

Answer 1

by using Pythagoras theorem find area area=1500cm3 x2=1500/60=5 perimeter =8×5+15×5+17×5=200cm

Answer 2

Answer:

200 cm

Step-by-step explanation:

By looking at the ratio we find that 8^2 + 15^2 = 17^2

thus conclude that it's a right angles triangle with hypotenuse 17

but the sides are given in ratio thus sides would be

15x 8x and 17x

thus area = 0.5 X base X height

here ; 1500 = 15x X 8x X 0.5

or , x^2 = 25

x = 5

now perimeter is 15x + 17x + 8x = 40 x = 40 X 5

Thus , 200cm
