Answer:
135ft²
Step-by-step explanation:
Width = w
Length = w + 6
Perimeter = 48
Perimeter = 2(l + w)
Perimeter = 2(w + 6 + w) = 48
2(2w + 6) = 48
4w + 12 = 48
4w = 48 - 12
4w = 36
w = 36/4
width = 9
length = w + 6 = 9 + 6 = 15
Area = length × width
= 15 × 9
= 135 ft²
Answer:
A = s²
Step-by-step explanation:
A = s² where s represents the side lengths
Since the side lengths of a square are always the same, you can use the formula A = s² for a square instead of using A=l(w)
Wouldn’t the answer be 8 and 3
