Question

The area of a square is (100x^2+100x+25)m^2. Find its perimeter when x=5cm

Answer 1

Answer:

Area = 100x² + 100x + 25

x = 5 cm

Substituting the value of x,

Area = 100(5)² + 100(5) + 25 = 2500 + 500 + 25

Area = 3025

Area of square = a²

3025 = a²

a = √3025

a = 55

Perimeter of square = 4a = 4×55 = 220 cm
