Did you notice the little box with corners marked in the angle down at the bottom ? That angle is a right angle, and <em>this triangle is a right triangle</em> !
This piece of information is a big help. It breaks the problem wide open. You know that in order to find the longest side of a right triangle . . .
-- Square the length of one short side. -- Square the length of the other short side. -- Add the two squares together. -- Take the square root of the sum.
One short side=48. Its square = 2,304. The other short side=48. Its square = 2,304. Add the two squares: 2,304 + 2,304 = 4,608
The square root of the sum = √4,608 = <em><u>67.88</u></em> (rounded)
<u />the answer may be 125 because 20 pieces of colored paper is only part and then the whole would be 125 because divided by is 5 so 25 times 5 is 125.
