Answer:
Step-by-step explanation:
A = 2(½(20)(15)) + 16(15 + 20 + 25) = 1,260 in²
It depends how many decimal points you are moving. If it's 1 decimal point then the point would move to the right and the answer would be 3246.50if it was two decimal places then it moves two to the right and the answer would 32465.0. But you don't need to put the .0 at the end so it will be 32465
Get total lengths by multiplying:
10 x 12.6 = 126
6 x 16.1 = 96.6
Add the total lengths together and divide by 16:
126 + 96.6 = 222.6
222.6 / 16 = 13.9125
Rounded to 2 decimal places = 13.91
answer: 13.91
Two negatives is a positive so the equation is Z+3/4=13/2
-3/4
Z=26/4-3/4
Z=23/4
