What is a trapezium?
It is a quadrilateral that has one pair of parallel sides and a height.
The area is calculated as: 1/2 x sum of the parallel sides x height.
Examples:
Area of a trapezium that has the parallel sides as 3 cm and 4 cm and a heght o 5 cm.
Area = 1/2 x (3 + 4) x 5
Area = 1/2 x 7 x 5
Area = 35/2 = 17.5 cm^2
We have,
Here's a diagram of how to draw two lines to make a square and two triangles in a trapezoid:

D __P_________Q____ C
To make a square andthe two triangles, draw a line from point A to P and from point B to Q.
Now,
We see that,
ABPQ is a square and ADP and BQC are two triangles.
Thus,
ABPQ is a square and ADP and BQC are two triangles.

Longest time to spin a regulation basketball on one finger, while maintaining the spin is 4 hr 15 min
What is Spin?
Spin is a conserved quantity carried by elementary particles, and thus by composite particles and atomic nuclei.
Spin is one of two types of angular momentum in quantum mechanics, the other being orbital angular momentum.
Spin is a conserved quantity carried by elementary particles, and thus by composite particles and atomic nuclei.
We need to find the time for longest spin of a basketball on one finger 255 minutes
The longest time to spin a regulation basketball on one finger, while maintaining the spin is 4 hr 15 min
Hence, longest time to spin a regulation basketball on one finger, while maintaining the spin is 4 hr 15 min

How many pieces of fabric are left over?
How many more pieces of fabric would you need to increase the size of the wall hanging?
Answers
The square wall hanging made from pieces of fabric will have an area of 1600 square inches. There will be 16 pieces of fabric left over. 1 more piece of fabric is needed to increase the size of the wall hanging.
The first thing to do in this process is to determine how many square pieces of fabric you can use to form a larger square. In order to have a square, you need the same number of pieces on each side, so the number of pieces used must be a perfect square. The largest perfect square less than or equal to 80 is 64 (which is 8^2), so you would use 64 pieces to form the wall hanging.
Therefore, the area of the wall hanging (which is side squared) is therefore 8 pieces x 5 inches x 8 pieces x 5 inches = 1600 square inches.
To find out how many pieces are left over, you subtract the number of pieces used from the total you started with, therefore 80 - 64 = 16 pieces of fabric are left over.
To increase the size of the wall hanging by one row and column (which remains a square), you would need to go up to the next perfect square which is 9^2 = 81, so you need 81 - 80 = 1 more piece of fabric.
