What is the dimension of a rectangle if the perimeter is 198
AfilCa [17]

Answer:

Length = 49.5 unit and width = 49.5 unit

Step-by-step explanation:

Given as , Perimeter of rectangle = 198 unit

so ,as Perimeter of rectangle = 2× ( Length + width)

Or,                                   198 = 2 ×  (Length + width)

Or,                                   \frac{198}{2} = length + width

So, length + width = 99 unit

Now to make area maximum

Length × width = maximum

Or, (99 - width ) × width = maximum

      99 Width - width² = maximum                              Let width = W

Now differentiate both side with respect to W

D(99W - W²)\frac{D(99w - w^2)}{Dw} = 0         as, constant diff is 0

So, 99 - 2w = 0

Or, w = \frac{99}{2}

Or, w = 49.5 unit    and L = 99- 4905 = 49.5 unit      Answer

Solve by addition method <br>3x+y=8 <br>2x-y=7
Vinil7 [7]

Answer:

(3,-1)

Step-by-step explanation:

So we have the system of equations:

3x+y=8\\2x-y=7

As directed, add straight down. The y-variable will cancel:

5x=15

Now, divide both sides by 5. The left cancels:

x=3

So x is 3.

Now, substitute 3 for x in either of the equations:

3x+y=8

Substitute 3 for x:

3(3)+y=8

Multiply:

9+y=8

Subtract 9 from both sides:

y=-1

So, our answer is: x=3, y=-1 or (3,-1).

And we are done :)
