Question

A rectangular field that is 119 yards in area is to be covered with sod.  It is kow that the field is 3 yards longer than twice the width  Find the dimensions of the field.

chihiroasleaf · Answer

the field is 3 yards longer than twice the width , it means
l = 2w + 3,

the area of the yards is l x w, 
so you have 
l x w = 119
(2w+3) w = 119

simplify and solve this equation, then you'll get w

how do i solve?

chihiroasleaf · Answer

use distributive property, then simplify the equation,
can you?

anonymous · Answer

i come up with the wrong answer :(

anonymous · Answer

i came up with 116 = 3x,,, the 38,6666

chihiroasleaf · Answer

(2w+3) w = 119
2w^2 + 3w = 119
2w^2 + 3w - 119 = 0

now, you have quadratic equation
now, solve the equation

anonymous · Answer

oh,,, ii was there once,, but i thought it was wrong

anonymous · Answer

so i have to use the quadratic formula?

chihiroasleaf · Answer

yes.., if it cannot be factorized
