Answer:
width=4in.
length=13in
Step-by-step explanation:
let the width of the rectangle be x
then the length will be x+9
Area= length×width
52= (x+9)x
52= x²+9x
x²+9x-52=0
x²+13x-4x-52=0
x(x+13) - 4(x+13)= 0
(x-4)(x+13)=0
x=4 or -13
dimension cannot be negative
hence x=4in
the width is 4in. and the length is 4+9=13in.

Answer:
3.3 :)
Step-by-step explanation:
The area is 81.25 m².
We find the area using the formula
A = 0.5*p*a, where p is the perimeter and a is the apothem.
Since this is a regular polygon, the perimeter is given by 10s, where s is the side length. This gives us:
A = 0.5(10s)(a) = 0.5(10*3.25)(5) = 81.25
