Given : The shape below is formed from a rectangle measuring 18 cm by 24cm from which a rectangle of length 8.6cm has been removed
To find : Work out the perimeter of the shape
Solution:
initial Perimeter of rectangle = 2 (24 + 18) = 84 cm
After removing rectangle of length 8.6 cm
two sides of 8.6 cm are added in perimeter
Perimeter of Shape
= 2 (24 + 18) + 8.6 + 8.6
= 84 + 17.2
= 101.2 cm
perimeter of the shape = 101.2 cm
