Question

perimeter of a square =(4a+8)cm .then it's dia.=?

Answer 1

Hello Dear!!!

here's your answer....

Given that,

perimeter is (4a+8)cm

take 4 as common..

4(a+2) is the perimeter.

Perimeter of a square = 4 times the side of a square.

side of a square = perimeter/4

side= 4(a+2) /4

side = a+2.

diagonal of a square is √2 times the side of a square.

diagonal = √2(a+2)

diagonal = (√2a+2√2)cm.
