First you have to divide the perimeter by 4, then square the solution. 81/4=20.25 20.25*20.25=410.0625 So the area equals 410.0625
81/2= 40.5
81/24=3.375
To find the percentage of 4 wrong out of 81 questions, divide the number of wrong answers by the total number of questions and then multiply by 100. So, (4 / 81) × 100 ≈ 4.94%. Therefore, approximately 4.94% of the answers were wrong.

81 Divide by three. 27,3 Divide by three. 9,3,3 Divide by three. 3,3,3,3 Stop.
Yes, 5 goes into 81. When you divide 81 by 5, the result is 16 with a remainder of 1. This means that 5 can fit into 81 a total of 16 times, but it does not divide evenly.
Yes, 17 goes into 81. When you divide 81 by 17, you get approximately 4.76, which means 17 fits into 81 four times with a remainder. Specifically, 17 multiplied by 4 equals 68, and 81 minus 68 leaves a remainder of 13.
