Question

the side of a triangle are in the ratio 2:3:5 and the perimeter is 200cm.Find it's area​

Answer 1

Answer:

3000 cm²

Step-by-step explanation:

ratio = 2:3:5

1st Side = 2x

2nd side = 3x

3rd side = 5x

perimeter = 2x + 3x+5x = 200

10 x= 200

x = 200/10

x = 20

So, 1st side = 2×20 = 40

2nd side = 3×20= 60

3rd side = 5×20 = 100

Area = ½ × base × height

½ × 100 × 60

1 × 50 × 60

= 3000 cm²
