Question

Base of a triangle is 9 and height is 10. Base of another triangle is 6 and height is 14. Find the ratio of areas of these triangles.

Answer 1

Answer:

Step-by-step explanation:

Let,

The triangle having 9 units as base and 5 units as height is ∆ ABC

And,the triangle having 10 units as base and 6 units as height is ∆ PQR

___________________

Now,

Area of ∆ ABC = (base × height)/2

Area of ∆ ABC =(9×5)/2

Area of ∆ ABC = 45/2 = 22.5 unit²

-----------------------

Area of ∆ PQR = (10×6)/2

Area of ∆ PQR = 10×3=30 unit²

--------------------

Ratio = 22.5 : 30

Ratio= 225:300

Ratio = 3:4
