Answer:
The answer to your question is:
Perimeter = 26.5 units
Area = 22.5 units²
Step-by-step explanation:
Data
A (5, 9)
B (8, 0)
C (0, 9)
Formula
d = 
dAB = 
dAB = 
dAB = 
dBC = 
dBC = 
dBC = 
dAC = 
dAC = 
dAC = 
Perimeter = 
Perimeter = 26.5 units
Area = 1/2 [ ( 5x0) + (8x9) + (0 x 9) - (5x 9) - (0x 0) - (8x9)]
= 1/2 [ 0 + 72 + 0 - 45 - 0 - 72]
= 1/2 [-45]
= 45/2
= 22.5 units²
Answer:
106
Step-by-step explanation:
You divide to find the quotient, the actual answer is 105.7, but I rounded it up for simplicity's sake.
I turn the mixed numbers into decimals before doing anything else.
11 2/5----> 57/5----> 11.4
4 2/7----> 30/7----> 4.29
2 1/7----> 15/7----> 2.14
11.4=q-4.29+2.14
11.4=q-2.15
13.55= q
13.55 converted to a fraction is 13 11⁄20
q=13 11⁄20
