Answer:
[tex]b = \dfrac{A}{h}[/tex]
Step-by-step explanation:
Given the formula for calculating the area of the rectangle as;
A = bh where;
b is the length of the base of the rectangle, and;
h is the height of the rectangle
Required
Make b the subject of the formula
Given
[tex]A = bh\\\\divide \ both \ sides \ by \ h\\\dfrac{A}{h} = \dfrac{bh}{h}\\ \dfrac{A}{h} = b\\Re-arrange;\\b = \dfrac{A}{h}[/tex]
Hence the value of b in terms of A and h is expressed as [tex]b = \dfrac{A}{h}[/tex]
