Question

Sides of triangle are in the ratio of 12:17:25and its perimetre is 540 cm . Find its area solve

Answer 1

Given

Sides of Triangle = 12, 17 , 25

Perimeter = 540.cm

12x + 17x + 25x = 540

54x= 540

X= 540 / 54

x = 10.cm

Sides

12.* 10 = 120
17*10.= 170
25*10 = 250

Semiperimeter = S / 2

Semiperimeter = 540./ 2

semiperimeter = 270


we use area formula

√s(s-a)(s-b) (s-c)

√270(270-120)(270-170)(270-250)

√270 *150 * 100* 20


answer = 9000cm²
