Good ol' Pythagorean Theorem.
To find the short side of the larger triangle, we'll use this equation:

You can solve the rest on your own.
Use the same type of equation for the smaller triangle, except your b would be the hypotenuse, so that equation would look something like this:

Hope it helped! Also, there seems to be a help video, if you didn't understand this explanation, why don't you go ahead and watch it?
The answer is <span>16x2 − 8x + 1

To be a perfect square trinomial, the rule must be used:
(a - b)² = a² - 2ab + b²
Let's check all choices
A. a = 7x, b = 4
(7x - 4)² = 49x² - 56x + 16
B. a = 2a, b = 5
(2a - 5)² = 4a² - 20a + 25
C. a = 5b, b = √10
(5b - √10)² = 25b² - 10√10 b + 10
D. a = 4x, b = 1
(4x - 1)² = 16x² - 8x + 1

Step-by-step explanation:
In this problem I'm assuming the office is rectangular.
so
The area of rectangle is equal to

where
L is the length of the rectangle
W is the width of the rectangle
In this problem we have

so
------> equation A
Find two possible dimensions of the office
case A) Assume a length side L and find the value of W in the equation A
so
For 
substitute in the equation and solve for W


The dimensions are
by 
case B) Assume a length side L and find the value of W in the equation A
so
For 
substitute in the equation and solve for W


The dimensions are
