Question

(1) The base and height of a triangle is 9 and 5 respectively. The
base and height of another triangle is 10 and 6 respectively. Find the
ratio of the area of the first triangle to the area of the other triangle.
(A) 95
(B) 5:3 (C) 3:4 (D) 4:3​

Answer 1

Answer:

here the answer . C. 3:4

Step-by-step explanation:

Let A1 be the area of first triangle and A2 be the area of other triangle Respectively.

Base and height of first triangle be b1 and h1 and Base and height of second of other triangle be b2 and h2 Respectively.

$\frac{a1}{a2} = \frac{b1 \times h1}{b2 \times h2} \\ \frac{a1}{a2} = \frac{9 \times 5}{10 \times 6} \\ \frac{a1}{a2} = \frac{45}{60} \\ \frac{a1}{ {a2} } = \frac{3}{4}$

The ratio of area of of first triangle to the area of other triangle is 3:4.
