The perimeter of a rectangular campsite is 64 cm and its area is 207 cm. Find the length and the breadth of the rectangle.
AlladinOne [14]
Perimeter Formula:
2l + 2b = 64


Area Formula:
l \times b = 207
Set perimeter Formula equal to b:
2l + 2b = 64 \\ 2(l + b) = 64 \\  l+ b = 32 \\ b = 32 - l
Plug formula for be we just made above into the area Formula:
(32 - l) \times l = 207


Solve for L (you'll have to use quadratic formula) then plug that back into the area Equation and solve for b.

Here's a link to where the problem has been explained before (they go into more detail than me).
