A rectangular astute has a fence around the perimeter. The length of the fence is 16x^7 and the width is 48x^4
To find the perimeter of the rectangle, we need to add up the lengths of all four sides.
The length of one side is 16x^7.
The width of one side is 48x^4.
Since the opposite sides of a rectangle are equal in length, we have:
Perimeter = 2(length) + 2(width)
= 2(16x^7) + 2(48x^4)
= 32x^7 + 96x^4
