The area of a rectangle is 40 aware feet what could be the prememiter of the rectangle

One possibility is 28 feet.

Step-by-step explanation:

Lets look at some  factors of 40

40 = 4 * 10   So 4 and 10 could be the width and length of the rectangle.

Then its perimeter = 2*length + 2*width

= 2*10 + 2*4

= 28 feet

answer: 12

step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
