Answer:
8 units
Step-by-step explanation:
The longer leg extends upward from y = -3 to y = 5, so its length is 8 units.
1 2/5 x 3 4/5 = 5.32 -- with calculator
----------------------------------------------------
You can change mixed fractions to improper fractions.
1 2/5 = 1 x 5 + 2 = 7 = 7/5
3 4/5 = 3 x 5 + 4 = 19 = 19/5
7/5 x 19/5 = 133/25 = 5.32
-----------------------------------------
To make sure you can then turn the improper fractions to decimals.
7/5 = 1.4
19/5 = 3.8
1.4 x 3.8 = 5.32
--------------------------
Whenever I get mixed fraction questions, I always check it in these different excess ways just to make sure :3 Hope it helped..
