Question

Sides of a triangle are in ratio 12:17:25 and its perimeter is 540 cm. Find its area.

Answer 1

let 1 side be 12x
let 2 side be 17x
let 3 side be 25x
12x+17x+25x=540
54x=540x
x=540/54
x= 10
now multiply 10to 12,17,25

Answer 2

draw a love triangle in marke size at 12x,17x and 25x . its perimeter is 540 cm what is the perimeter of triangle perimeter of triangle :
now first you find its types so 12 x + 17 X + 25 x = 540
54= 540
x=540/54
x=10
X1=10+12
X2=10+17
so on
when it's it's side find, you know that area of triangle is 3 into size so answer is with you .
