A construction company is starting to build a new house. They need to put tape around the site to begin. The new home site is 20 meters wide by 40 meter long rectangle. The company already has 100 meters of tape.
How much more tape does the company need to tape the site?
To calculate the perimeter of the rectangle, we add the length of all four sides:
20 + 20 + 40 + 40 = 120
So the perimeter of the rectangle is 120 meters.
Since the company already has 100 meters of tape, they need:
120 - 100 = 20 meters
They need 20 more meters of tape to tape the entire site.
