Work out the perimeter

The shape below is formed from a rectangle measuring 18 cm by 24cm from which a rectangle of length 8.6cm has been removed

Step-by-step explanation:

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
