QUESTION : Carmen wants to mount an 18 x18 cm square picture on a square board that is four times of the area of the picture.
a) What is the area of the picture?
I answered 324 cm because when you square 18 it totals to 324.
b) What is the area of the board?
For now, I know that the board is 4 times the area of the picture, and so I multiplied 324 to 4 and so the answer is 1296.
c) What are the dimensions of the board?
I answered 36 because if you will find the square root of 1296 the answer will be for sure 36.
