Question

Base of a triangle is 18 and height is 10. Base of another triangle is 20 and height is 12. Find the ratio of areas of these triangles.​

Answer 1

Answer:

3:4

Step-by-step explanation:

area of a triangle = 1/2 base x height

For the first triangle,

Given:

Base = 18

Height = 10

area = 1/2 x 18 x 10

        = 90

For the second triangle,

Given:

Base = 20

Height = 12

area = 1/2 x 20 x 12

        = 120

∴ the ratio of these triangles = 90:120 = 3:4
