Question

the sides of triangle are in the ratio 25 : 7 : 25 the and its perimeter is 540 m. find the sides of triangle and its area ?​

Answer 1

Answer:

sides are 250, 170,120 area of the triangle is 9000 m²

Step-by-step explanation:

the correct question is

the sides of a triangle are in the ratio 25:17:12 the and its perimeter is 540 m. find the sides of the triangle and its area?​

answer- let the common ratio of sides be x

so the sides are

25x, 17x, 12x

25x+17x+12x=540

54x=540

x=540/54

x=10

so sides are

25x=25×10=250

17x=17×10=170

12x=12×10=120

semiperimeter=perimeter/2

semiperimeter=540/2

semiperimeter=270

area of triangle=√s(s-a)(s-b)(s-c)

=√270(270-250)(270-170)(270-120)

=√270×20×100×150

=√81000000

=9000 m²
