Question

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

Area of 1st triangle / area of 2nd traingle = (1/2b1 × h1) / (1/2 b2×h2) =》 (1/2 × 9 ×5) / ( 1/2 × 10 × 6)

=》 (45/2) / ( 30)

=》 3/4

.: The ratio of two triangles is 3/4

Answer 2

Answer:

Let ABC and PQR be two right triangles with AB ⊥ BC and PQ ⊥ QR.

Given:

BC = 9, AB = 5, PQ = 6 and QR = 10.

∴A(△ABC)/A(△PQR)

=AB×BC/PQ×QR

=5×9/6×10

=3/4
