Question

Above are two different models of the same rectangular dog run. If the area of the model on the left is 54 sq cm, what is the area of the model on the right?

Answer 1

48 sq cm

Explanation:

The smaller square is 3' x 3' = 9 square feet.

The larger square is 9' x 9' = 81 square feet.

9 goes into 81 exactly 9 times (81 / 9 = 9), so we could just multiply the 54 cm by 9 and get your answer in centimetres.

54 x 9 = 486 cm
