Find the perimeter of the square if it is 6 cm longer than one of the sides.
| November 22, 2020 | education
Let’s say the side of the square is x cm, then the perimeter is (x + 6) cm. Also, the perimeter is 2 (x + x) = 4x according to the formula 2 (a + b). It turns out
x + 6 = 4x
4x-x = 6
3x = 6
x = 6: 3
x = 2 (side of the square)
Hence P = 2 (2 + 2) = 8cm
Answer: 8cm
