## What is the ratio of the area?

Area ratio is the sides ratio squared! When A1 and A2 are areas and S1 and S2 are measures of corresponding segments. Given the similar pentagons shown, find the ratio of their areas. If the ratio of the areas of two similar parallelograms is 49:121, find the ratio of their bases.

## How do you find ratio of area?

**In rare and extreme cases, black widow spider venom poisoning may lead to seizures and even death**. Death generally doesn’t occur in healthy adults. Young people, the elderly, and those with weakened immune systems are more susceptible to serious complications and death from a black widow spider bite.

## What is the ratio of sides to area?

If two polygons are similar, the ratio of their areas is **Equal to the square of the ratio of their corresponding sides**.

## What is the ratio of a rectangle?

For example, the aspect ratio of a rectangle is **The ratio of its longer side to its shorter side**—the ratio of width to height, when the rectangle is oriented as a “landscape”. The aspect ratio is most often expressed as two integer numbers separated by a colon (x:y), less commonly as a simple or decimal fraction.

## How do you find the ratio of the area with the scale factor?

Areas: If the scale factor of the sides of two similar polygons is , then the ratio of the areas is **( m n ) 2** (Area of Similar Polygons Theorem). You square the ratio because area is a two-dimensional measurement.

## How do you find the ratio of two sides?

Areas: If the scale factor of the sides of two similar polygons is , then the ratio of the areas is **( m n ) 2** (Area of Similar Polygons Theorem). You square the ratio because area is a two-dimensional measurement.

## How do you find the ratio of a triangle?

The most common way to write a ratio is **As a fraction**, 3/6. We could also write it using the word “to,” as “3 to 6.” Finally, we could write this ratio using a colon between the two numbers, 3:6. Be sure you understand that these are all ways to write the same number.

## What is the ratio of a triangle?

Remembering the 30-60-90 triangle rules is a matter of remembering the ratio of **1: √3 : 2**, and knowing that the shortest side length is always opposite the shortest angle (30°) and the longest side length is always opposite the largest angle (90°).
