suter [353]
I believe it’s A, because for C, 12 and 12 are both positive, and for d, -12 and -12 are both negative, and so since 3 and -3 are not both negative nor positives, the answer would be Absolute Values. I think. Sorry if I’m wrong. Please correct me if I’m wrong, but I hope this helped!!

A. The perimeter of quadrilaterals are same when x=2.

B. The area of quadrilaterals are same when x=4.6

<u>Step-by-step explanation</u>:

A. <u>Perimeter of the quadrilaterals must be equal.</u>

  • Perimeter of square is 4a.
  • where, a = 6
  • Perimeter of rectangle is 2(l+b).
  • where, l = 2 and b = (3x+4)

Perimeter of square = Perimeter of rectangle

4(6) = 2(2+3x+4)

⇒ 24 = 2(3x+6)

⇒ 24 = 6x + 12

⇒ 6x = 12

⇒ x = 12/6

x = 2

For x=2, the perimeters of both the quadrilaterals are same.

B. <u>Area of the quadrilaterals must be equal.</u>

  • Area of square is a².
  • where, a = 6.
  • Area of rectangle is l\timesb.
  • where, l = 2 and b = (3x+4)

Area of square = Area of rectangle

(6)² = 2(3x+4)

36 = 6x+8

6x = 28

x = 28/6

x = 4.6

For x=4.6, the area of both the quadrilaterals are same.
