If I'm right, mark me as brainliest

Answer 2

Answer:

Step-by-step explanation:

Given,

In ∆ABC

Base  and height = 9 and 5

In ∆PQR

Base  and height = 15 and 6

To Find,

The Ratio of areas of these triangles. ​

Formula to be used,

Area of triangle, A = 1/2 × b × h

Solution,

Let the triangles be ∆ABC and ∆PQR.

Area of triangle, A = 1/2 × b × h

= Area of ∆ABC/Area of ∆PQR.

= 1/2 × b × h/1/2 × b × h

= (1/2 × 5 × 9)/(1/2 × 15 × 6)

= 1/2

Hence, the ratio of Area of ∆ABC : Area of ∆PQR IS 1 : 2.
