Let sides of triangle are 3x,4x,5x
Sum of sides=3x+4x+5x=12x(perimeter)
Acc to question
12x=288 (given)
X=288÷12=24
Sides are 3×24=72
4×=96
5×=120
Semiperimeter=(72+96+120)÷2=144
Area=sqare root of 144(144-72)(144-96)(144-120)=sqare root of 144×72×48×24
=sqare root of 11943936=3456sq m

A+b+c = 288 meters a:b:c = 3:4:5

let a= 3x b = 4 x c = 5 x where x is some number a+b+c = x(3+4+5) = 12 x So 12 x = 288 meters x = 24 meters So a = 72 m b = 96 m c = 120 meters If the sides of a triangle are in the ratio of 3 : 4 : 5, then it is a right angle trianlgle. Its area is 1/2 a b . (a, b are smaller sides. c hypotenuse) So Area = 1/2 72 * 96 = 3456 meter² IF the sides are not in a right angle triangle, the n find s and use formula for area
