Use the figure to find the measures.
Solve for x.
5
A = 20
A=4
X=

x = sqrt(5)

Step-by-step explanation:

The ratio of the areas is equal to the ratio of the side lengths squared

20      5^2

=

4          x^2

Using cross products

20 x^2 = 4 * 5^2

20x^2 = 4*25

20x^2 = 100

Divide by 20

20x^2 = 100/20

x^2 = 5

Take the square root of each side

sqrt(x^2) = sqrt(5)

x = sqrt(5)
