Let the length be l.
Formula of perimeter is P= 2(length +width )
1313 =2 (l+w)
l = \frac{1313}{2}-w
And the formula of area of rectangle = length times width .
A = l*w
A= (\frac{1313}{2}-w )*w
A = \frac{1313w}{2} -w^2
And that's the required objective function .
The equation represents parabola and a parabola is maximum at its vertex .
And the formula of vertex is
w = -\frac{b}{2a} =-\frac{1313}{4}
Substituting this value of w in the formula of area, we will get
A= \frac{1313*1313}{8} -(\frac{1313}{4})^2
Area= \frac{1723969}{16}=107748 \ square \ units .
D. DOQ & BOQ together equals 90 degrees
A) You divide the previous number in the sequence with 6. (31104/6 = 5184, 5184/6 = 864). Follow this pattern and you can easy find the rest.
b) You divide the previous number by 2. (14/2 = 7, 7/2=7/2)... and so on
=2ab - 20a -5a +10 -ab - b
= ab - 25a - b + 10
