Question

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 1

Answer:

3:4

Step-by-step explanation:

given:-

b1=9m, h1=5m

b1=10m, h2=6m

A1 = ½b1h1

A1 = (9×5)/2 =45/2 m²

A2 = ½b2h2

A2 = (10×6)/2 = 60/2 m²

A1 : A2 = A1/A2 = 45/2÷60/2 = 45/2 × 2/60 = 45/60=3/4

A1:A2 = 3:4

Answer 2

First triangle ...

Base = 9

Height = 5

Area = 9×5 = 45

Second triangle....

Base = 10

Height = 6

Area = 10 ×6 = 60

Ratio of area = 45:60

= (45:60)÷ 5 =( 9:12) ÷ 3 = 3:4
