Find the dimensions of the green space if it's length must be 40 ft less then twice its width with a total area of 33,600 ft^2 I found the equation but I don't know how to find the final width and length

length = 240 units

Width = 140 units

Step-by-step explanation:

Width = w

Length = 2w - 40 ft

Area  = 33,600 square feet

length * width = 33600

(2w - 40) *w = 33600

2w² - 40w = 33600

2w² - 40w - 33600 = 0

Divide the equation by 2

w² - 20w - 16800 = 0

Sum = -20

Product = -16800

Factors = -140 , 120

w² -140w + 120w - 140 * 120 = 0

w(w - 140) + 120(w - 140) = 0

(w - 140)(w + 120) = 0

w +120 = 0 is ignored because width won't be in negative.

w - 140 = 0

w = 140 units

length = 2*140 - 40

           = 280 - 40

           = 240 units

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
