Question

Find the area of the triangle whose sides are in the ratio 2:3.5 and the perimeter is 200 cm. Find its area.​

Answer 1

Answer:

let the common ratio of sides of triangle=x

=>first side=2x

second side=3x

third side=5x

now perimeter of triangle=200cm

=>2x+3x+5x=200cm

=>10x=200cm

=>x=20cm

=>first side=2x=2×20cm=40cm

second side=3x=3×20cm=60cm

third side=5x=5×20cm=100cm
