Answer 2

Answer:

The required ratio is 3 : 4.

Step-by-step explanation:

Let,

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

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

Now,

Area of A ABC = (base x height)/2

Area of A ABC =(9×5)/2

Area of A ABC = 45/2 = 22.5 unit²

Area of A PQR = (10×6)/2

Area of A PQR = 10×3=30 unit²

Ratio = 22.5:30

Ratio= 225:300

Ratio = 3:4
