Question

For his art project, Dorian is using square tiles of different sizes and colors to make a mosaic. The first three tiles are: 1. A = 5 cm2 2. A = 7 cm2 3. A = 9 cm2

which tile's side lengths will Dorian need to estimate?

Answer 1

3cm²

Explanation:

Since the sizes are square tiles, to know the tile's side lengths that Dorian need to estimate, we will use the formula for calculating the area of q square

Area of a square = L²

L is the side length of the tiles

For the tiles with area 7cm²

7 = L²

L² = 7

L = √7

L = 2.65cm

For tiles with area 5cm²

5 = L²

L² = 5

L = √5

L = 2.24cm

For tiles with area 9cm²

9 = L²

L² = 9

L = √9

L = 3.0cm

Since for all the square tiles the length of the tile is ≤ 3 cm, then the tile's side lengths that Dorian will need to estimate is approximately 3cm
