Question

Base of a triangle is 12 and height is 5. Base of another triangle is 15 and height is 3. Find the ratio of areas of these triangles.​

Answer 1

→Answer :

=

Area(△PQR)

Area(△ABC)

=

×5×9

=

3

Hence, Ratio of Area of △ABC:Area of △PQR=3:4

Answer 2

Step-by-step explanation:

Area of the 1st triangle is 1/2×b×h

1/2×12×5=30cm square

Area of the 2nd triangle is 1/2×b×h

1/2×15×3=22.5 cm square

Not sure about the ratio. sorry!

I think we should cancel these 2 areas to find the ratio
