Answer:
16 units
Step-by-step explanation:
this rectangle is nice to us. its side lines are clearly parallel to the coordinate axis.
A starts at x=1, y=2.
B is straight above with x=1, y=7
so, how long is AB ? it is just the difference in y direction 7-2=5.
C is then on the same y height as B, and is just a bit to the right (bigger x value) with x=4, y=7
what is the distance BC ? just the difference in x 4-1=3.
since it is a rectangle, the other 2 sides are a "copy" of these first 2 sides.
so, another 5 and 3.
therefore, the perimeter of the rectangle is
2×5 + 2×3 = 16 units of the coordinate system.
The second answer is correct.
Step-by-step explanation:
a^2 +b^2 = c^2
b^2 = c^2 - a^2
3 - solving for h
A = bh
h = A ÷h
4 - solving for r
I = prt
r = I÷ pt
5- solving for b
A= 1/2 bh
can rewrite as
A = bh ÷2
b = 2A ÷ h
