Question

base of a triangle is 8 centimetre and height is 10 centimetre base of another triangle is 12 centimetre and the height is 15 centimetre find the ratio of these triangles​

Answer 1

Answer:

The ratio of the areas of the triangles is 3 : 4

Step-by-step explanation :

Find the area of first triangle :

Base of triangle = 9cm

Height of triangle = 5cm

Area of triangle = 1 / 2 × base × height

⇒ 1 / 2 × 9 × 5

⇒ 45 / 2

Find the area of second triangle :

Base of triangle = 10 cm

Height of triangle = 6 cm

Area of triangle = 1 / 2 × base × height

⇒ 1 / 2 × 10 × 6

⇒ 30 cm

Find the ratio of the areas of both the triangles ;

Ratio = Area of first Δ / Area of 2nd Δ

Ratio = 45 / 2 × 1 / 30

Ratio = 3 / 4

Ratio = 3 : 4

Hence, the required ratio is 3 : 4
