Answer:
Part A : Area = Xft . X ft
Part B: A= 6ft . 4ft
Part C: P = xft +x ft + xft +x ft
Step-by-step explanation:
Hi, for part A and part B we have to apply the area formula (for a rectangle)
Area = L . W
Where:
L: Lenght
W: Width
Replacing with the values given:
Part A= Area of the painting (grey area)
A = Xft . X ft
Part B = Area of the frame (white section)
A= 6ft . 4ft
For part C we have to apply the perimeter formula:
Perimeter = 2 L + 2 W
Replacing with the values given:
P = 2xft +2xft
or
P = xft +x ft + xft +x ft (sum of all sides)
