Question

A rectangle has an area of 36 inches squared. Write an equation to show how the length (l) varies inversely the width (w).

What is the equation of the line?

Answer 1

Let x be Length
Y be Width

area= xy
xy= 36

x=36/y

hence the width and length are inversely related to each other

Answer 2

Question -

A rectangle has an area of 36 inches squared. Write an equation to show how the length (l) varies inversely the width (w).

What is the equation of the line?


A) W = L/36 

B) L = W/36 

C) L = Wx36 

D) L = 36/W



Answer : $\bold{L = 36/W}$


Explanation -

Area of a rectangle = length x width

Area = 36 inches

Length = Area / width

Length = 36/W.


Hence :

Answer : L = 36/W
