Question

Perimeter and area of a rectangle 11 cm by 19.3cm

Answer 1

Answer:

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
