Answer:
The diagonal of the bottom side is 17.5 cm.
Step-by-step explanation:
The diagonal of a rectangle is a straight line that joins any two of its edges.
Given that: length = 15 cm, width = 4 cm, and h = 3 cm.
The bottom side is the flat rectangular surface (base) of length 15 cm and width 4 cm which excludes the height.
So that the diagonal, s, can be determined by Pythagoras theorem.
[tex]s^{2}[/tex] = [tex]17^{2}[/tex] + [tex]4^{2}[/tex]
= 289 + 16
= 305
s = [tex]\sqrt{305}[/tex]
= 17.46425
The diagonal of the bottom side is 17.5 cm.
