The length of a rectangle is five times its width. If the area of the rectangle is 500 cm^2 find its perimeter.

Perimeter = 120

Step-by-step explanation:

5w = L

L * w = 500

5w(w) = 500

w^2 = 100

w = 10

5(10) = L

50 = L

Perimeter = 2(50) + 2(10)

Perimeter = 120

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
