Calculaye the perimeter and area of these composite shapes

For this case we have that the perimeter of the figure is given by the sum of the lengths of the sides, that is:

Thus, the perimeter of the figure is 64 centimeters.

Now, we find the area of the figure:

We have that by definition, the area of a rectangle is given by:

Where:

a and b are the sides of the rectangle

We have 4 vertical rectangles from left to right:

Thus, the total area is

The perimeter of the figure is 64 centimeters.

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
