The diagram shows 3 identical circles inside a rectangle - Edexcel - GCSE Maths - Question 21 - 2017 - Paper 2

The height of the rectangle is the diameter of one circle, which is:

$\text{Height} = \text{Diameter} = 48 \text{ mm}$

The area of the rectangle can be calculated using the formula:

$\text{Area} = \text{Length} \times \text{Height}$

Substituting the values:

$\text{Area} = 96 \text{ mm} \times 48 \text{ mm} = 4608 \text{ mm}^2$

Rounding to three significant figures, the area of the rectangle is:

[ 4600 \text{ mm}^2 ]
