Question

1) Base of a triangle is 9 and base of another triangle is 10. If the heights of triangles are equal.
Write the ratio of areas of these triangles.​

Answer 1

Answer:

Its Simple

Step-by-step explanation:

A1 = Area of Smaller Triangle = ?

A2 = Area of Bigger Triangle = ?

S1 = Side of Smaller Triangle = 9 units

S2 = Side of Bigger Triangle = 10 units

Therefore,

$\frac{A1}{A2}$ = $\frac{(S1)^{2} }{(S2)^{2} }$

Therefore,

$\frac{A1}{A2}$ = $\frac{(9)^{2} }{(10)^{2} }$

Therefore,

$\frac{A1}{A2}$ = $\frac{81}{100}$

Final Answer = A1 : A2 = 81 : 100
