Question

the length of a rugby league field is 52 meters longer than its width "w" . The area of a rugb league field is 8160 square meters. Find the dimensions of the field

Answer 1

A=8160=w*(w+52)=w^2 +52w
it is a quadratic equation - solve it for w (need positive value only)
let me know if you have a problem... :)

Answer 2

i dont know how to solve quadratic equations

Answer 3

you equation looks like:
w^2 +52w-8160=0
w=[-52+/- sq.rt( 52^2-4*(8160))]/2
w=[-52+/-sq.rt(10,144)]/2
w=(-52 +/-188)/2
you choose only positive value (width can not be negative),
so w=(188-52)/2
w=68
if w=68, length =68+52=120

Answer 4

don't forget to put meters in your answer :)
