Mr.Calvillo wants to enclose a rectangular area for a garden space of a given square footage.The length of the plot will vary inversely as the width.If he decides on a width of 18 feet,the garden will be 30 feet long.How long will a 45 foot wide garden be?
LET AREA =A ..THIS IS CONSTANT AS GIVEN
LET LENGTH =L
LET WITH =W
AREA=A=LENGTH*WIDTH=L*W=CONSTANT...HENCE L=A/W....OR L VARIES INVERSELY AS W.
CASE 1
L=30....W=18...HENCE A=30*18=540
CASE 2
L=?...W=45
A=540=L*45
L=540/45=12
