If the ratio of the areas of two similar polygons is 25: 49, what is the ratio of the corresponding side length

5:7

Step-by-step explanation:

Ratio of the areas of similar shapes is equal to the square of the scale:

A₂ / A₁ = r²

Ratio of the side lengths of similar shapes is equal to the scale:

s₂ / s₁ = r

Therefore:

A₂ / A₁ = (s₂ / s₁)²

25/49 = (s₂ / s₁)²

s₂ / s₁ = 5/7

The ratio of the side lengths is 5:7.

5 : 7

Step-by-step explanation:

Given 2 similar figures then

ratio of sides = a : b

ratio of areas = a² : b²

Here the ratio of areas = 25 : 49, hence

ratio of sides = : = 5 : 7

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

answer: .64
