Perimeter of rectangle is 208p² - 160p + 272 centimeters
Given:
Width of rectangle = (10p+6)(10p+6) centimeters
Length of rectangle = (2p-10)(2p−10) centimeters
Find:
Perimeter of rectangle
Computation:
Width of rectangle = (10p+6)(10p+6)
Width of rectangle = 100p² + 120p + 36
Length of rectangle = (2p-10)(2p−10)
Length of rectangle = 4p² - 40p + 100
Perimeter of rectangle = 2(l + b)
Perimeter of rectangle = 2[(4p² - 40p + 100) + (100p² + 120p + 36)]
Perimeter of rectangle = 2[104p² - 80p + 136]
Perimeter of rectangle = 208p² - 160p + 272 centimeters
