Question

The base and height of a triangle are in the ratio of 3:5 . If area is 120 sq.cm,find its base and height

Answer 1

Step-by-step explanation:

Let the base be 3x and height be 5x .

Area =120cm^2

Area of triangle =1/2×base×height

therefore

1/2×3x×5x=120

15/2x^2=120

x^2=120×2/15

x^2=16

x=4

now

base=3x=3×4=12cm

height=5x=5×4=20cm
