Question:
Mr.Jon's garden covered 300 square feet. If the width was 5 feet less than the length, find the measurements of the garden.
Answer:
Area of the garden = 300 square feet.
Assume that length = 'x' feet
Then width = x - 5 feet
Area = length * width
that is...
300 = x * (x -5 )
==>
Subtract 300 from both sides....
==>
==> , which is a quadratic equation...
You can solve it using quadratic formula
==>
==> or
==> or
==> or
Hence the value of x
That is length = 20 feet or 15feet
Measurements:
When length = 20 feet, width = 20 - 5 = 15 feet
When length = -15 feet, width = -15 -5 = -20 feet.
Hope you found the explanation useful.
