Question

1. find the perimeter of the rectangle.

13 cm
area = 52 cm²

Explanation:

Step1: Find missing side length.

Let the unknown side be $w$. Area formula: $A = l \times w$.
$w = \frac{A}{l} = \frac{52}{13} = 4$ cm

Step2: Calculate rectangle perimeter.

Perimeter formula: $P = 2(l + w)$
$P = 2(13 + 4) = 2 \times 17 = 30$ cm

Answer:

30 cm
