Question

Practice set 1.1
gle
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

Explanation:

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

♦ Solution :-

See the picture you will understand.

Hence, Ratio of Area of ∆ABC to ∆PQR is 3:4

Hope it helps..

Thanks. (:

Answer 2

Explanation:

Area of the the ∆=1/2*9*5=45/2

____________________________

Area of another∆=1/2*10*6

=30

_____________________________

ratio if the areas=45/2:30

=45:60

=3:4
