Chapter 11.7, Problem 12WE

To determine

To Find: The ratio of their areas.

Answer to Problem 12WE

  $x^2:y^2$

Explanation of Solution

Given: The length of two similar traingles are $x^{2}andxy$

Since the triangles are similar.

Ratio of their length is

  $\frac{x^2}{xy}=\frac{x}{y}$

Ratio of area is

  $a^2:b^2=x^2:y^2$

Hence, the ratio of their areas is $x^2:y^2$.
