`35.75`
`km^2`

46)
`24.5`
`km^2`

Explanation:

------------------------------

The formula to find the area of a triangle is
`A=(1)/(2)bh` where
`b` stands for the base and
`h` stands for the height.

So, let's solve and find out the answer.

--------------->>>>

45)

`A=(1)/(2)(11)(6.5)`

`A=(1)/(2)(71.5)`

`A=35.75`

The area of this triangle is
`35.75`
`km^2`

--------------->>>>

46)

`A=(1)/(2) (10)(4.9)`

`A=(1)/(2) (49)`

`A=24.5`

The area of this triangle is
`24.5`
`km^2`
