Question

Mariska was decorating her room. She arranged 63 picture tiles on a wall in the shape of a rectangle. How many rows of tiles could be on the wall?

Answer 1

The number of rows could be `1,3,7,9,21,63`

Explanation:

The area of a rectangle is `A = l xx b`

Find the factors of `63`. Each factor could be the number of rows of tiles:

`63 = 7 xx 9`

`63 = 3 xx21`

`63 = 63xx1`

The number of rows could be `1,3,7,9,21,63`
