Answer:
l = 35 inches and b = 16 inches
Step-by-step explanation:
Let length be b and width be b.
The area of a rectangle is 560 square inches.
Length is 3 more twice the width.
l = 2b+3 ....(1)
We know that,
Area = length × width
560 = (2b+3)b
[tex]2b^2+3b-560=0\\\\b=16,-17.5[/tex]
Put b = 16 in equation (1).
l = 2(16)+3
= 35 inches
So, the length is 35 inches and the width is 16 inches.
