Question

The length of the sides of a triangle are in the ratio of 3:4:5 and if the perimeter is 48cm then find its area

Answer 1

Answer:

96cm^2

Step-by-step explanation:

let the sides be 3x 4x and 5x

3x+4x+5x=perimeter=48cm

12x=48

x=4

so the sides are 12cm,16cm and 20cm

now u will notice that these sides are of a right angled triangle

since (12)^2+(16)^2=(20)^2

hence area = 1/2 x base x height

1/2*12*16

96cm^2
