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

[tex]P=2a+2b[/tex]

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:

[tex]A=a\times b[/tex]

Then for each rectangle, we have:

First rectangle, sides: 5ft and 12.5 ft

-Perimeter:

[tex]P=2\times5+2\times12.5=35[/tex]

Then, the perimeter of the first rectangle equals 35 feet

-Area:

[tex]A=5\times12.5=62.5[/tex]

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

Second rectangle, sides: 15m and 8.2m

-Perimeter:

[tex]P=2\times15+2\times8.2=46.4[/tex]

Then, the perimeter of the rectangle equals 46.4 m

-Area:

[tex]A=15\times8.2=123[/tex]

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