Answer:
area=135
Step-by-step explanation:
The width is 9 and six more would make the length 15 which 15+15=30 and 9+9=18 which added together is 48 which would make the perimeter 48 which is what they told us the perimeter is so to find the area you multiply the 15 and 9 to get 135.
135ft²
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
surface areas:
1. 94 ft
2. 96 cm
volumes:
