Question

Area of a square tile is the same as the area of a rectangular tile that is 18 inches long and 8 inches wide

What is the side length of the square tile?

Answer 1

The length of the square is 12 inches.

Explanation:

Area of square = Area of rectangle

Area of rectangle = Length × Breadth

⇒ 18 × 8

⇒ 144 in²

★ Area of square = Side × Side

⇒ 144 = Side²

⇒ Side = √144

⇒ Side = 12 inches

Therefore, the length of the square is 12 inches.

Answer 2

• 12 in

Explanation:

Area of rectangle:

• A = lw = 18*8 = 144 in²

Area of square:

• A = a²
• a² = 144
• a = √144
• a = 12 in
