First off, pay attention in school.... Answer: measure the length and the width of the roof. Then you want to multiply those together. that is the square foot amount you will need.
30 cm
No. "Feet" tells you a length or distance, like the length of a rope, or the distance from home to school. "Square feet" tells you an area, like how much carpet you need to cover a floor, or how much land you own.
The question says "Ken doesn't eat the crust on is pizza. For each pizza estimate the LENGTH of pizza he doesn't eat. Then calculate the Length. question A's radius is: 32cm. question B's radius is: 12.7cm. Please Help Me on This.. They didn't teach us any of this at school yet. ~Swimmer.
4,200 square feet. Multiply length by width - the result is the area in square feet.
I would use meters.
You would typically use a measuring tape or a ruler to measure the length of a school hallway in meters, centimeters, or millimeters. If you need to measure longer distances in kilometers, you might use a measuring wheel or a GPS device.
The meter.
Metres would probably be the most convenient.
The appropriate unit is a metre.
A rule doesn't exist !
Assuming that the hallway is 30 m long. 30mx100= 3000 cm . Then divide 3000 cm by 2,54= result: 1181,1023622047244094488188976378 in = (Firstly you have to use any measuring tool to find the length of the hallway in meters, or you may get the final reading in inches if the measuring tape tool has divisions in centimeters and inches. Usually they have divisions on foot and cm)
Every school is different. The layout of every school is also different. So you will need to find the distance from your classroom to the principal's office in your own school. Ask your teacher's permission to use a tape measure or yardstick to measure the hallway length between the two points.
. The answer is 458 m.
Meters! Because if you used centimeter you would get about 800+ centimeters but probably about 20-30 meters. So meters would be more precise. Hope this helped!
Alot.
