Question

1. find the perimeter of this figure (for perimeter add all sides)

9 cm
7 cm

Explanation:

Step1: Identify side - lengths

The rectangle has two sides of length 9 cm and two sides of length 7 cm.

Step2: Apply perimeter formula

The perimeter $P$ of a rectangle is $P = 2l+2w$, where $l = 9$ cm and $w = 7$ cm. So $P=2\times9 + 2\times7$.

Step3: Calculate

$2\times9=18$ and $2\times7 = 14$. Then $P=18 + 14=32$ cm.

Answer:

32 cm
