Perimeter is the distance around the outside of a shape. For example, if you walk around the edge of a playground, you're measuring its perimeter. Area is the amount of space inside a shape. For example, if you want to put new tiles on your kitchen floor, you need to know the area of the room to know how many tiles to buy. Created by Sal Khan.

What is true about the ratio of the area of similar triangles? Answer: If 2 triangles are similar, their areas . are the square of that similarity ratio (scale factor) For instance if the similarity ratio of 2 triangles is $$\frac 3 4 $$ , then their areas have a ratio of $$\frac {3^2}{ 4^2} = \frac {9}{16} $$ . Let's look at the two similar triangles below to see this rule in …Find step-by-step Geometry solutions and your answer to the following textbook question: The areas of two similar octagons are 112 in.$^{2}$ and 63 $\mathrm{in.}^{2}$.
