Kal is decorating the outside edge of a square bulletin board. He needs to know the side length of the bulletin board. The area of the bulletin board is n square feet. Which expression shows the side length, in feet, of the bulletin board?

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

i have no idea just need points sorry

step-by-step explanation:

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.

i’m kinda new to precal but your answer should be 21. hope i got it right.
