Yes it is a Trapezoid. First, find Perimeter (P), since it's easiest. P = sum of all 4 sides, so:
P = 9.8 + 3.5 + 6.53 + 6.33 = 26.16 yds
Lastly, we need the Area (A) of a trap., which is the average of the parallel bases (usually top and bottom) multiplied by height (h). In our case a1 & a2, and average means add them then divide by 2, so our formula becomes:
A = [(a1+a2)/2]×h
A = [(9.8+3.5)/2]×5.6
A = 37.24 sq.yds.
y - 90 - 1/9 = 12.45 Step-by-step explanation: i think so if im incorrect
Look at this it explains how to solve it.
The first contract can go to any of 12 firms. The second can go to any of the remaining 11 firms, and so on. Finally, the 4th contract can go to any of the 9 firms that don't yet have a contract.
The number of ways the contracts can be awarded is
... 12×11×10×9 = 11,880
Answer: B. The product of P and S is always a rational number.
Step-by-step explanation: The product AND sum of two rational numbers will ALWAYS be rational.
