The length of a rectangular room is 6.5 m in the width is 4.23 meters. What is the perimeter of the room? Report the answer with

LuckyWell [14K]

Perimeter is equal to 2l+2w, or 2 times the length plus 2 times the width.

So to solve for this you'd take 2(6.5) + 2(4.23).
2(6.5)= 13
2(4.23)= 8.46

13+8.46= 21.46 meters.

Based on this, the answer is C.

$y=a(x-h)^{2}+k$

Where h is the x-coordinate of the vextex and k is the y-coordinate of the vextex.

2. You know that the vertex of this parabola is at (-2, 5), then, susbtitute this point into the equation. Then, you obtain:

$y=3(x+2)^{2}+5$

3. Therefore, the answer is the option C.
