Answer:
5 un^2
Step-by-step explanation:
the liens from (0, 0) to (1, 3) and (1, 3) to (4, 2) are perpendicular meaning that the angle at (1, 3) is a right angle
to find the lengths of the sides we must use the pythagorean theorem
a^2 + b^2 = c^2
for the leftmost side
we have 1^2 + 3^2 = c^2
1 + 9 = 10
c^2 = 10
c = sqrt(10)
for the top side
we have
the same thing
1^2 + 3^2 = c^2
1 + 9 = 10
c^2 = 10
c = sqrt(10)
you must multiple sqrt(10) by sqrt(10) and then by 1/2
sqrt(10) * sqrt(10) is 10
10 * 1/2 is 5
the area is 5 un^2
If you're asking if 3/4 is less than 1/2, then it's a true statement.

Answer:
96 yards
Step-by-step explanation:
This is basically just a huge addition problem that we can tackle (heh) in our heads.
If we gain yards, then we add.
If we lose yards, then we subtract.
If we started out at 50, the expression is
.
We can use the associative property of addition to simplify this. I'm just grouping together things that look easy to do in my head.
Hope this helped!
