Ok so you know the equation for the formula for the area of a rectangle. So you can write the equation as 2.5 times X is equal to 20.5. We want to isolate X, so divide each side by 2.5 and you find the length or X!

anonymous · Answer

length =a*w
since your area is 20.5 and your width is 2.5 therefore, 
length=20.5*2.5

@hellokitty357 That is incorrect. You would do 20.5/2.5 instead of multiplying them
