Step-by-step explanation:
it is like a regular addition of numbers. you add the different positions.
3x + 7x = 10x
-y + y = 0
-5 + 15 = 10
so, D. is the right answer : 10x = 10
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 .
