Find the area of the room by multiplying the length by the width:

Area of room = 20 x 12 = 240 square feet.

Find the area of the tile: 2x 2 = 4 square feet.

To find the number of tiles divide the area of the room by the area of a tile:

240/4 = 60

They will need 60 tiles.

3. A ladder is placed 5ft away from a building. The ladder comes up to 12 ft on the side of the
irina [24]

Answer:

13 feet long

Step-by-step explanation:

This situation forms a right triangle, where the ladder is the hypotenuse, the distance away from the building is the short leg, and the height to the side of the building is the long leg.

Use the pythagorean theorem, and solve for c, the hypotenuse:

a² + b² = c²

5² + 12² = c²

25 + 144 = c²

169 = c²

13 = c

So, the ladder is 13 feet long
