A rectangular piece of paper is 10 inches wide and 16 inches long. What is its perimeter?

Sagot :

Since the paper is rectangular, opposite sides of the paper are congruent.

The perimeter of the paper is given by the sum of all sides, so we have:

[tex]\begin{gathered} P=2\cdot length+2\cdot width\\ \\ P=2\cdot16+2\cdot10\\ \\ P=32+20\\ \\ P=52\text{ inches} \end{gathered}[/tex]

Therefore the perimeter of the paper is 52 inches.
