Question

find the value of the ratio (red to blue) of the areas of the similar figures. Write the ratio as a fraction in simplest form.

Answer 1

16/225

Explanation:

Ratio of the area of similar figures = ratio of the square of any of their corresponding side lengths

Thus:

Area of red triangle : area of blue triangle = square of side length of red triangle : square of side length of blue triangle

Area of red : area of blue = 4²/15²

= 16/225
