Answer:
The measurement which Jane finds to be 10 meters is the length of the banner.
Step-by-step explanation:
The measurement of 10 meters which Jane found after measuring how long the banner is before painting is the LENGTH of the banner.
This is clear from the unit of what she finds (meters). It only indicates the measurement of one part of the banner, even though a banner has two parts, the length and width.
It is possible to find the AREA, or PERIMETER, or LENGTH.
But what she finds is the LENGTH of the banner. If it was Area or Perimeter, the unit would have been square meters.
The answer is B i believe
No they don't.
Phythagorean triple is when the sum of the squares of two numbers is equal to the square of another number.
20^2 + 24^2 = 400 + 576 = 976
31^2 = 961
20^2 + 24^2 should have been equal to 31^2 but that's not the case. So, the side's length don't form a triple.
Hope it helped!
