Answer:
Each side has a length of 11yd
Step-by-step explanation:
To calculate the side of the square we have to apply the formula of the perimeter of a square and clear s
p = perimeter = 44yd
s = side
p = s * 4
p /4 = s
we replace with known values
44yd / 4 = s
11yd = s
Each side has a length of 11yd
Step-by-step explanation:
5 + d > 5 - d
5 + d + d > 5
5 + 2d > 5
2d > 5 - 5
2d > 0
d > 0 ÷ 2
d > 0
3^-5 is the answer to this expression.
