Question

Base of triangle is 9 and height is 5. Base of another triangle is 20 and height is 6. Find the ratio of areas of these triangle.​

Answer 1

Here's your answer.. ⬇⬇

♦ Given :- Let The triangle be ∆ABC and ∆PQR.

In ∆ABC,

Base of ∆ABC is BC = 9cm

Altitude of ∆ABC is AE = 5cm

In ∆PQR,

Base is QR = 10cm

Altitude is PM = 6cm

♦ To Find :- Ratio of Area of ∆ABC and ∆PQR

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
