Explanation
The ratio of the area of two similar triangles is equal to the square of the ratio of any pair of the corresponding sides of the similar triangles.
[tex]\frac{area\text{ 1}}{area\text{ 2}}=\left(s.f\right)^2[/tex]
so
Step 1
Let
[tex]\begin{gathered} area1=153\text{\lparen in}^2) \\ area2=272\text{ \lparen in}^2) \end{gathered}[/tex]
replace fo find the s.f
[tex]\frac{area\text{ 1}}{area\text{ 2}}=\left(s.f\right)^2[/tex]
