Question

Find the perimeter and area of each rectangle. Be sure to show all work! 1. 5 ft and 12.5 ft2. 15 m and 8.2 m

Answer 1

We can find the perimeter of a rectangle by means of the formula:

`P=2a+2b`

Where a and b are the length of the sides of the rectangle

To find the area of the rectangle, we can use the formula:

`A=a* b`

Then for each rectangle, we have:

First rectangle, sides: 5ft and 12.5 ft

-Perimeter:

`P=2*5+2*12.5=35`

Then, the perimeter of the first rectangle equals 35 feet

-Area:

`A=5*12.5=62.5`

Then, the area of the rectangle equals 62.5 ft^2

Second rectangle, sides: 15m and 8.2m

-Perimeter:

`P=2*15+2*8.2=46.4`

Then, the perimeter of the rectangle equals 46.4 m

-Area:

`A=15*8.2=123`

Then, the area of this rectangle equals 123 m^2
