Question

when estimating measurements using commonly available non - standard instruments, its essential to understand the role of precision in measurement.
floor tile area: the area of a single floor tile (usually square or rectangular).
estimating measurements:
suppose you want to estimate the area of a room floor using floor tiles.
heres how you can do it:

1. count the number of floor tiles along a wall.
2. measure the length and width of a single tile (in inches or centimeters).
3. multiply the number of tiles by the area of one tile to estimate the total floor area.

lets practice!
if we count 20 tiles, each measuring 12 inches by 12 inches, the estimated area is ____ square inches.
remember to use a comma in your answer if needed. example: 5,321

Explanation:

Step1: Calculate area of one tile

A tile is square (12 in × 12 in), so area of one tile is \( 12 \times 12 = 144 \) square inches.

Step2: Multiply by number of tiles

There are 20 tiles, so total area is \( 20 \times 144 = 2880 \).

Answer:

2,880
