The area of a rectangular computer chip is 112a^3b^2 square microns. what is the length if the width is 8ab

Area of rectangle is given by:

This is the concept of algebra:

Area=length*width

thus:

rewrite the above for length we get:

length = (Area) / (width)

given that:

Area=112a^3b^2

Width=8ab

the length will be:

length = (112a^3b^2) / (8ab)

length=14a^2b

the answer is length=14a^2b units
