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

Question

Square 1: 3ft Square 2: 9ft

Answer 1

Looking at the question, if I am understanding this correctly, you have a 3 foot tall x 3 foot wide square and a 9 foot tall x 9 foot wide square?

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
