Answer:
45) [tex]35.75[/tex] [tex]km^2[/tex]
46) [tex]24.5[/tex] [tex]km^2[/tex]
Step-by-step explanation:
------------------------------
The formula to find the area of a triangle is [tex]A=\frac{1}{2}bh[/tex] where [tex]b[/tex] stands for the base and [tex]h[/tex] stands for the height.
So, let's solve and find out the answer.
--------------->>>>
45)
[tex]A=\frac{1}{2}(11)(6.5)[/tex]
[tex]A=\frac{1}{2}(71.5)[/tex]
[tex]A=35.75[/tex]
The area of this triangle is [tex]35.75[/tex] [tex]km^2[/tex]
--------------->>>>
46)
[tex]A=\frac{1}{2} (10)(4.9)[/tex]
[tex]A=\frac{1}{2} (49)[/tex]
[tex]A=24.5[/tex]
The area of this triangle is [tex]24.5[/tex] [tex]km^2[/tex]
------------------------------
