Perimeter: 60.6cm
Area: 212.3cm
Step-by-step explanation:
When calulating the perimeter, you are adding the length of all the sides together. Since the figure is a rectangle, two two pairs of sides will be different lengths. Solving is as follows:
P = 11+11+19.3+19.3 or P=11 (2) + 19.3 (2) = 60.6
With area, you need the total amount of mass, so you would multiply two sides. In this case, the two are 11cm and 19.3cm.
A = 11 (19.3) cm = 212.3
