Why?
The first thing we need to do is find the area of the triangle, we can to that by subtracting the area of ABCD from ACBE, then, we can use the formulas to calculate the area for both triangle and rectangle to find "f" and "g".
Calculating we have:

Now, we can calculate "f" by using the formula to calculate the area of the triangle:

Now, finding "g" by using the formula to calculate the area of the rectangle, we have:

Hence, we have that:

Have a nice day!
I believe that the answer is l<span>ength of PQ = length of P′Q′ since they are the same sides on both shapes

The system has a unique solution. Because the augmented matrix can be reduced to the form of the identity matrix.
<h3>What exactly is a linear system?</h3>
It is an equation system in which the maximum power of the variable is always 1. A figure with only one dimension and no breadth. It is made up of infinite dots placed side by side.
The augmented matrix must be reduced to the form of the identity matrix since there are three pivots one in each row.
Whatever is on the opposite side of the equal sign, there is a solution that is specific and exists.
Hence, the system has a unique solution.
