Question

find the area of the rectangle
a = ? m²
7 m

Explanation:

Step1: Recall the formula for the area of a rectangle

The area \( A \) of a rectangle is given by the formula \( A = \text{length} \times \text{width} \).

Step2: Identify the length and width

From the diagram, the length of the rectangle is \( 11 \, \text{m} \) (assuming the bottom side is 11 m, as it's a rectangle and the side given is 7 m which is the width) and the width is \( 7 \, \text{m} \).

Step3: Calculate the area

Substitute the values into the formula: \( A = 11 \times 7 \).
\( 11 \times 7 = 77 \).

Answer:

\( 77 \)
