Question

The perimeter of a square is (4x+20)cm. What
will be the length of its diagonal?
​

Answer 1

Answer:

Step-by-step explanation:Perimeter of a square = 4 * side

4x + 20 = side * 4

side = 4x + 20 / 4

side = 4 ( x + 5 ) / 4

∴side = x + 5 cm.

Now,

Diagonal of a square = √2 * side

Diagonal = √2 * ( x + 5 ) cm.
