Answer:
The length as an algebraic expression in y is 
ft
Step-by-step explanation:
The measure of the width of the computer desk = y feet
The measure of the length of the desk = width + 2 1/4 ft
⇒Measure of Length = ft
Hence, the length as an algebraic expression in y is ft

The height of the triangular base of the pyramid is calculated through the equation,
h = (cos x)(18 in)
where h is height and x is half of the angle of the triangle. Since the triangle is equilateral, the value of x is 30°. Substituting,
h = (cos 30°)(18 in)
h = 15.59 in
Thus, the height of the base is approximately 15.59 inches.
30-[18-(24\4)] = 18
