Question

question 21 (3 points) you are going to put new tile flooring in your room. you want to estimate the area of the floor by counting the tiles that are currently along the wall. your room is in the shape of a rectangle. you count 12 tiles on one side of the room and 15 on another side. using the dimensions of your current tile in the picture below, estimate the area of your room. remember that area of a rectangle can be found by multiplying length and width. 8 in 8 in 64 in² 180 in² 1440 in² 11520 in²

Explanation:

Step1: Find the length of the room in inches

The number of tiles along one side is 15 and each tile is 8 inches long. So the length $L = 15\times8=120$ inches.

Step2: Find the width of the room in inches

The number of tiles along the other side is 12 and each tile is 8 inches long. So the width $W = 12\times8 = 96$ inches.

Step3: Calculate the area of the room

The area of a rectangle $A = L\times W$. Substituting the values of $L$ and $W$, we get $A=120\times96 = 11520$ square - inches.

Answer:

11520 in²
