Base of a triangle is 9 and height is 5. Base of another triangle is 10 and height is 6. Find the ratio of areas of these triangles.

Answer»

Let the base, height and area of the first triangle be b1 , h1 , and A1 respectively. Let the base, height and area of the second triangle be b2 , h2 and A2 respectively.

A1/A2 = (b1 x h1)/(b2 x h2) ...[Ratio of areas of two tringles is equal to the product of their bases and corresponding ]

A1/A2 = (9 x 5)/(10 x 6)

= 45/60

A1/A2 = 3/4

∴ The ratio of areas of the tringles is 3:4.
