Answer:

84.14 square units, total

Step-by-step explanation:

Use the formulas for area of the figures you're interested in.

Rectangle Area

A = LW

Circle Area

A = πr^2

Your rectangle area will be ...

A = 5 × 14 = 70 . . . . square units

The area of a full circle with diameter 6 (radius = 6/2 = 3) will be ...

A = π × 3^2 = 9π

The area of a semicircle of that size is half that:

semicircle area = 9π/2 = 4.5π

Then the total area of the two figures is ...

70 + 4.5π ≈ 70 +14.14 = 84.14 . . . square units

H/2 + 21 - k if h=20 and k=89

Hoochie [10]

$\huge\text{Hey there!}$

$\mathsf{\dfrac{h}{2} + 21 - k\ if\ h=20\ and\ k=89}$

$\textsf{If h = 20 and k = 89, the SUBSTITUTE it for where they are in the equation}$

$\mathsf{\dfrac{10}{2}+21 - 89}$

$\mathsf{\dfrac{20}{2}= \bf 10}$

$\mathsf{\bold{10}+21 - 89}$

$\mathsf{10+21=\bf 31}$

$\mathsf{\bold{31}-89= \underline{ANSWER}}$

$\mathsf{= \bf -58}$

$\boxed{\boxed{\large\text{Answer: \huge \bf -58}}}\huge\checkmark$
