45) 35.75 km^2

46) 24.5 km^2

Step-by-step explanation:

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

The formula to find the area of a triangle is $A=\frac{1}{2}bh$ where stands for the base and stands for the height.

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

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

45)

$A=\frac{1}{2}(11)(6.5)$

$A=\frac{1}{2}(71.5)$

A=35.75

The area of this triangle is 35.75 km^2

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

46)

$A=\frac{1}{2} (10)(4.9)$

$A=\frac{1}{2} (49)$

A=24.5

The area of this triangle is 24.5 km^2

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

Hope this is helpful
