Question

side of two similar triangles are 3cm,and 5cm ,if what is the ratio of their areas​

Answer 1

Area of triangle with side 3cm = 1/2×base×height

=1/2×3×3

=1/2×9=4.5sq.cm

Area of triangle with side 5cm =

1/2×base×height

=1/2×5×5

=1/2×25

=12.5

Therefore,ratio between the 2 triangle's area =4.5/12.5

=9/25

=9:25

Answer 2

Answer:

1 : 1

Explanation:

Area of triangle = 1/2 × base × height

= 1/2 × 3cm × 5cm

= 15cm²/2

= 7.5cm²

If both triangle side is similar.so, their area also be similar.

Ratio = 7.5cm²/7.5cm²

= 1/1

= 1 : 1
