Question

the perimeter of square is (4x +20) cm what will be the length of it's diagonal​

Answer 1

_____________________

Given that perimeter P = 4x+20

If square has a side a

we know that perimeter P= 4a

➠4a = 4x+20

➠a =4x/4+20/4

➠a= 4(x+5)/4

➠a= x+5

we know that if a is the side of square,then length of diagonal D = √2 a

D= √2 a

Substituting the value of a in this above eqution we get

D= √2(x+5)
