A. Area of a square= side length squared
=> A= (x-3)^2
= x^2-6x+9
b. Area of rectangle= larger side length* smaller side length
=> A= x(x-5)
= x^2-5x
c. If both areas equal then expressions for areas equal as well.
x^2-5x= x^2-6x+9
=>x=9

A student desk has an area of 15/16 square meters. The width of the desk is 5/4 meters. What is the length of the desk in meters

olga_2 [115]

For this case, the first thing we are going to do is model the desk as a rectangle.
The area of the rectangle is given by:
A = w * l
Where,
w: width
l: length
Clearing we have:
l = A / w
Substituting values:
l = (15/16) / (5/4)
Rewriting we have:
l = (15/16) * (4/5)
Simplifying we have:
l = (3/4) m
Answer:
The length of the desk in meters is:
l = (3/4) m
