A rectangle has an area A=L%2AW where L is length and W is width
given:
a rectangle with a width of W=12cm( cm=centimeters)
has an area of A=312cm%5E2
A=L%2AW plug in given values
312cm%5E2=L%2A12cm ...solve for L
312cm%5E2%2F12cm=L
312cm%5Ecross%282%291%2F12cross%28cm%29=L
%28312%2F12%29cm=L
26cm=L
