What is the preimter and area of a rectangle that is 30 inchs long and 39 inchs wide

Multiple both numbers by 2 since there are 2 of them on a rectangle. After, add them.

30 x 2 = 60
39 x 2 = 78
60 + 78 = 138

And never forget to label your units!

The perimeter of the rectangle is 138 inches.

To get the area, multiply the sides by each other.

30 x 39 = 1170

The area of the rectangle is 1170 inches^2, or 1170 inches squared.

Perimeter is 138 (60*2+39*2)

Area is 1170 (30*39)
