Question

the length of a rectangle is 6 meters more than its width. If the area is 40 square meters, what are the length and width?

Answer 1

\[x+\]\[w+6 = length\]
\[So width is 4 meters and length is 10 meters\]

Answer 2

let the width be x and length be x+6

area=l*w
40=(x+6)(x)
x^2+6x=40
x^2+6x-40=0
now solve

Answer 3

x(x+6)=40 ==> x^2 +6x-40=0 ===>(x-4)(x+10) = 10 ===> x=4 ( forget the negative solution) ===> width = 4 ===> length =10

Answer 4

width=4m,
length=10m
