Answer:
52.80
Step-by-step explanation:
We can determine the side length of the painting
A = s^2 for a square painting
144 = s^2
Taking the square root of each side
sqrt(144) = sqrt(s^2)
12 = s
We need to find the perimeter for the painting
For a square painting
P =4s
P = 4*12
P = 48
Multiplying by the cost per inch
1.10 * 48 =52.8
Answer:
$52.80
Step-by-step explanation:
Area = side²
144 = side²
side = 12 in
Perimeter = 4 × side
= 4 × 12 = 48 in
Cost = 48 × 1.10
= 52.80
