Let:
L = Length
W = Width
The length is 7cm longer than its width, so:
The area is given by:
Therefore:
Solve for W using the quadratic formula:
Therefore:
W = 12.38238 since a negative width wouldn't make any sense
and:
Answer:
W = 12.38238 m
L = 19.38238 m

Answer:
6400
Step-by-step explanation:
Given the profit function ;
P(c) = –20c2 + 320c + 5,120
The maximum value is given by :
f(h) ; where, h = - b /2a
From P(C) ; a = - 20 ; b = 320
h = - b / 2a = - 320 / 2(-20) = - 320 / 40 = 8
c = h
P(8) = –20(8)² + 320(8) + 5,120
P(8) = - 1280 + 2560 + 5120
= 6400
