Answer:
Area = 77 yd²
Step-by-step explanation:
Width = w
Length = w+4
Perimeter =36
Perimeter = L + L + w + w
36 = w+4+w+4+w+w
4w+8 =36
Subtract 8 from both sides
4w = 36 - 8
4w =28
Divide both sides by 4
W= 28/4
W= 7yd
Therefore length = w+4 = 7+4 = 11 yd
Area = length x width
Area = 11× 7
Area = 77 yd²

Answer:
There are two types of variables-independent and dependent. ... Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.
