1. The area of a rectangle is 20, and its diagonal is√104. Find its dimensions and perimeter. Long side:
Shorter side:
Perimeter:

2. A coin, thrown upward at time t=0 from an office in the Empire State Building, has height in feet above the ground t seconds later given by

h(t)=−16t^2+112t+288=−16(t−9)(t+2).

a) From what height is the coin thrown? Include units in your answer.
b) At what time does the coin hit the ground? Include units in your answer.

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.
