Question

The diagram shows 3 identical circles inside a rectangle. Each circle touches the other two circles and the sides of a rectangle, as shown in the diagram. The radius of each circle is 2mm. Work out the exact area of the rectangle. Give your answer in the form (see pic) where a and b are integers.

Answer 1

Answer:

one side is 12 as the radius is 2 so x 2 for diameter which is 4. there are 3 circles so times it by 3 which = 12.

the other side is 4 as one circle daimeter is 4.

4 x 12 = 48.
