Step-by-step explanation:
a) The shape of the window is rectangular. To find the area of the window, we will apply the area of rectangle
Area = length × width
length = 67 in
width = 36 in
Area = 67 × 36
Area of the window = 2412 in²
Perimeter of a rectagle = 2(length + width)
Perimeter of the window = 2(67 + 36) = 2(103)
Perimeter of the window = 206 inches
b) if the window glass is replaced, we need to calulate the area of the window the previous glass occupied.
Hence, to know the amount of glass needed, the measure to be used is area
c) For a silver wire to be placed round the window, we need to know the total length of the window frame. This total length is perimeter
Hence, the measure required is the perimeter
