Question

The area of a rectangle is 0.8 square units. The length is 3.2 units and the width is x units. What is the value of x?

Answer 1

So remember the rectangle area formula $A=lw$ . Since we have the area, 0.8, and the sides, 3.2 and x, we can plug them in to solve for x:

$0.8=3.2x$

For this, just divide both sides by 3.2, and your answer will be $0.25=x$

Answer 2

A = LW

LW = A

3.2 * x = 0.8

x = 0.8/3.2

x = 0.25

Answer: 0.25 units
