For the triangles ABC and MNP m∠A = m∠M, AB = 16, AC = 10, MN = 7, MP = 24. Find the ratio of the A△MNP and A△ABC .

Digiron [165]

Answer:

Ratio of area of triangles MNP and ABC is 1.05

Step-by-step explanation:

There are 2 triangles ABC and MNP.

We are given that ,m∠A = m∠M.

AB = 16 and AC = 10.

MN = 7 and MP = 24.

Area of a triangle ∝ Product of any two sides.

So area of triangle ABC ∝ 16 $\times 10$

Area of triangle ABC = 160 $\times k$ ,

where k is a constant.

So area of triangle MNP ∝ 7 $\times 24$

Area of triangle MNP = 168 $\times k$

So ratio of area of triangles = $\frac{Area of MNP}{Area of ABC}$

= $\frac{168}{160}$

= 1.05
