Sagot :
The expression that represents the perimeter of the rectangle is: (164p² + 292p + 298) cm.
What is the Perimeter of a Rectangle?
Perimeter of rectangle = 2(length + width).
Given:
- Length = (p+10)(p+10) cm
- Width = (9p+7)(9p+7) cm
Thus:
Perimeter = 2[(p+10)(p+10) + (9p+7)(9p+7)]
Perimeter = 2(p² + 20p + 100 + 81p² + 126p + 49)
Add like terms
Perimeter = 2(82p² + 146p + 149)
Perimeter = 164p² + 292p + 298
Thus, the expression that represents the perimeter of the rectangle is: (164p² + 292p + 298) cm.
