Chapter 5: Q11 (page 169)

Find the perimeter of $▱ RISK$ , if $RI = 17$ and $IS = 13$ .

Short Answer

Expert verified

The perimeter of a parallelogram is 60.

Step by step solution

Step 1. Consider a diagram below.

Step 2. Perimeter of a parallelogram.

The perimeter of a parallelogram with sides a and b is given by, $P = 2 (a + b)$ .

Step 3. Apply a definition of perimeter of parallelogram.

Consider $▱ R I S K$ such that $R I = 17$ and $I S = 13$ . Therefore, the perimeter of a parallelogram is

$\begin{matrix} P = 2 (R I + I S) \\ = 2 (17 + 13) \\ = 2 \times 30 \\ = 60 \end{matrix}$

Therefore, the perimeter of a parallelogram is 60.
