A rectangular park has an area of 250 square feet. The length of the park is 7 feet more then twice the width, w of the park. Wh
ich equations, in terms of w, model this situation
2 answers:
Area = length * width
width = w
length = 2w+7
A = (2w+7) * w
250 =2w^2+7w
0 = 2w^2 +7w-250
w is the width, hence length is 2w + 7 ( 7 more than twice the width )
area = length × width = w( 2w + 7 ) = 250
2w² + 7w - 250 = 0 ← in standard form
