PO =

1 answer:

8 0

Using mid point formula.

In which we have

Q(-4,5)=(6+x/2) , (2+y/2)

-4=6+x/2 and 5 =2+y/2

-8=6+x and 10=2+y

x=-14 and y=8

Therefore the required value of R{-14,8}

A playground is constructed with the dimensions and shapes shown below

Alchen [17]

check the picture below.

so the playground is really just 3 rectangles and one triangle, now the triangle has a base of 8 and a height of 6. We can simply get the area of each figure, sum them up and that's the area of the playground.

$\bf \stackrel{\textit{area of the triangle}}{\cfrac{1}{2}(8)(6)}~~+~~\stackrel{\textit{rectangle}}{(8\cdot 8)}~~+~~\stackrel{\textit{rectangle}}{(6\cdot 6)}~~+~~\stackrel{\textit{rectangle}}{(9\cdot 4)}
