2x=36.75
x=18.375
y=31.5-18.375=13.125
check : 18.375+13.125=31.5,

What is the perimeter of the rectangle? Write your answer in scientific notation. The area is 2.76 x 10 pw12 the width is 4.6 x
Elanso [62]
The caret (^) is the symbol conventionally used to indicate an exponent.

You have
  area = 2.76·10^12
  width = 4.6·10^5

You want to find the perimeter of the rectangle with these dimensions.

The perimeter of a rectangle is twice the sum of length and width.
  perimeter = 2*(length + width)
The length can be figured from the area using the formula for area.
  area = length*width
  area/width = length . . . . . . . . . divide by width
Filling in the numbers, we have
  perimeter = 2*((2.76·10^12)/(4.6·10^5) +(4.6·10^5))
  perimeter = 2*(6.0·10^6 +0.46·10^6)
  perimeter = 2*6.46·10^6 = 1.292·10^7

The perimeter of the rectangle is ...
  1.292·10^7
