Work out the following problem by hand. Consider the overdetermined system [1/1][x]= [9/5] whose coefficient matrix obviously ha
s full rank.
a. Before you do anything else, guess the least-squares solution of the system.
b. Calculate a full QR decomposition of the coefficient matrix, where Q is 2 × 2 and R is 2 × 1. Use the QR decomposition to calculate the least-squares solution. Deduce the norm of the residual without calculating the residual directly.

Answer:
2 units tall by 1 unit wide
Step-by-step explanation:
On the given rectangle it tell you the conversion to m is 1 unit = 2 m.
The new figure that needs to be drawn has a conversion of 1 unit = 8m.
So, the fist thing we need to do is calculate the m on the width at the height of the original, which is 16 by 8.
looking at this we can now convert this measurement into our new conversion of 1 unit = 8 m. We can do this by dividing the height and width separately.
Ex:
Since 16 is divided by 8 two times so that gives us the answer of 2 units.
8 is divisible by 8 one time so that gives us the width of 1 unit
if this is confusing just think of it like: x= for the height or x =
for the width.
