### How do you find the area of similar figures?

## How do you find the area of similar figures?

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. For example, for any two similar triangles ΔABC and ΔDEF, Area of ΔABC/Area of ΔDEF = (AB)2/(DE)2 = (BC)2/(EF)2 = (AC)2(DF)2.

## How do you calculate area to perimeter ratio?

The perimeter of a shape is the measure of the length of a shape around its outermost extremities. The area of a shape is the amount of two-dimensional space that it covers. The ratio of the perimeter to the area of a shape is simply the perimeter divided by the area. This is easily calculated.

## How do you find a similar perimeter?

Perimeters of Similar Figures of their perimeters is equal to the ratio of their corresponding side lengths.

## What is the formula of similar triangle?

If the two sides of a triangle are in the same proportion of the two sides of another triangle, and the angle inscribed by the two sides in both the triangle are equal, then two triangles are said to be similar. Thus, if ∠A = ∠X and AB/XY = AC/XZ then ΔABC ~ΔXYZ.

## What is the relation between perimeter and area of two similar triangles?

Note: The ratios of corresponding sides of the two triangles are in equal if they are similar. The perimeter of the triangle is equal to the sum of their sides.

## What is the ratio of their areas?

In two similar triangles, the ratio of their areas is the square of the ratio of their sides. Try this The two triangles below are similar. Drag any orange dot at P,Q,R. Note the ratio of the two corresponding sides and the ratio of the areas.

## What is the ratio of an area?

In two similar triangles, the ratio of their areas is the square of the ratio of their sides.

## What is the formula for perimeter?

Perimeter, Area, and Volume

Table 1 . Perimeter Formulas | ||
---|---|---|

Shape | Formula | Variables |

Square | P=4s | s is the length of the side of the square. |

Rectangle | P=2L+2W | L and W are the lengths of the rectangle’s sides (length and width). |

Triangle | a+b+c | a,b , and c are the side lengths. |

## How do you find the missing area in similar shapes?

Similar areas

- We already know that if two shapes are similar their corresponding sides are in the same ratio and their corresponding angles are equal.
- When calculating a missing area, we need to calculate the Area Scale Factor.
- Area Scale Factor (ASF) = (Linear Scale Factor) 2
- The figures below are similar.

## How to find the perimeter of a similar figure?

1. If the perimeters of two similar figures are in the ratio 2. If the areas of two similar figures are in the ratio The two rectangles given below are similar. Find the perimeter of the rectangle EFGH. Because the above rectangles ABCD and EFGH are similar, the lengths of the corresponding sides will be proportional. Multiply each side by 12.

## How to calculate the area of a similar figure?

Area : If two similar figures have a scale factor of a : b, then the ratio of their areas is a 2 : b 2. Note : 1. If the perimeters of two similar figures are in the ratio . a : b, then their areas will be in the ratio. a 2: b 2. 2. If the areas of two similar figures are in the ratio a : b, then their perimeters will be in the ratio. √a : √b

## How to calculate the perimeter and area of a rectangle?
