5. a)
Step 1: Identify the length and width of the rectangle from the image.
Length L=12.8 m
Width W=7.5 m
Step 2: Use the formula for the perimeter of a rectangle, P=2(L+W).
Substitute the given values into the formula.
P=2(12.8m+7.5m)
Step 3: Perform the addition inside the parentheses.
P=2(20.3m)
Step 4: Perform the multiplication.
P=40.6 m
The perimeter of the rectangle is 40.6m.
