Question

The base and height of the triangle are in ratio 3:5 and its area is 120cm^2 then find its base and height

Answer 1

Answer:

Step-by-step explanation:

Let base = 3x

   height = 5x

area of triangle = 120 cm^2

=>  b x h/2         = 120

=> 3x*5x            = 120*2

=> 15 x^2           = 240

=> x^2                = 240/15

=> x^2                = 16

=>            x         = 4

base = 3 x 4 = 12

height = 5 x 4 = 20
