\frac{4 \sqrt{400} }{4 \sqrt{5} } =  \frac{ \sqrt{400} }{ \sqrt{5} } = \\  \frac{20}{ \sqrt{5} } *  \frac{ \sqrt{5} }{ \sqrt{5} } = \frac{20 \sqrt{5} }{5} } = 4  \sqrt{5}
Thank you.

<h3>Answer:  11/20</h3>

=====================================================

Work Shown:

x = unknown horizontal length

1/5 = 0.2

Perimeter = 2*(width + length)

P = 2*(0.2 + x)

P = 0.4 + 2x

Set this equal to the given perimeter of 1 & 1/2 = 1.5 and solve for x

0.4 + 2x = 1.5

2x = 1.5-0.4

2x = 1.1

x = (1.1)/2

x = 0.55

x = 55/100

x = (5*11)/(5*20)

x = 11/20

The sum of the measures of the interior angles of a convex polygon is 1080° Classify the polygon by the number of sides​
lozanna [386]

Answer:

(n-2)×180=1080

180n -360=1080

180n = 1080+360

180n =1440

dividing by 180

n=8

hence it is a regular polygon with 8 sides .I.e it is an octagon

Step-by-step explanation:

we are given the total interior angles in the polygon and we know that the formula to find the total interior angles of a polygon is (n-2) ×180

where n is the number of sides
