Question

The perimeter of a square with side = 10 unit will be ……………………..

90 units


320 units


40 units

Answer 1

Step-by-step explanation:

Since all sides of a square are equal, we only need one side to find its perimeter. The perimeter of the given square is: a + a + a + a = 4 a units. Hence, the formula of the perimeter of a square = 4 × (length of any one side).
