A rectangular garden has a perimeter of 48 cm and an area of 140 sq. cm. What is the length of this garden?
Length of garden is
Let the length be
Hence, perimeter is
Hence multiplying each term by
Hence, dimensions of garden are
The garden has sides of 14cm and 10cm. Length is 14cm.
We know that it is a rectangle, so each pair of opposite sides are the same length. We denote one set of sides length
Therefore, the perimeter is given by
The area of a rectangle is given by the product of it's length and breadth, ie
Use quadratic formula:
