Answer:
Part 1) 
Part 2) 
Part 3) 
part 4) 
Part 5) 
Step-by-step explanation:
we know that
In a rectangle opposite sides are parallel and congruent
The measure of each interior angle is 90 degrees
The diagonals are congruent and bisect each other
step 1
Find the length of side PR
we know that
----> by opposite sides
we have

therefore

step 2
Find the length of side PQ
we know that
----> by opposite sides
we have

therefore

step 3
Find the length of diagonal PS
we know that
---> the diagonals bisect each other
we have
---> given problem
therefore

step 4
Find the length of diagonal QR
we know that
---> the diagonals are congruent
we have

therefore

step 5
Find the length of RT
we know that
---> the diagonals bisect each other
we have

substitute

<u>Answer:</u>
D. A = 6n²
<u>Step-by-step explanation:</u>
area of 1 side = n x n = n²
There are 6 sides in a cube.
∴ Total surface area = 6 x n²
A = 6n²
