Question

the perimeter of a square is 36 cm find the length of its diagonals

Answer 1

Given Perimeter = 36 cm

Now ,
4× Side = 36 cm
Side = 36/4 cm
Side = 9 cm

Now ,

H² = B² + P²
H² = 9²+9²
H² = 81+81
H² = 162
H =√162

The diagonal is of √162 cm

Answer 2

hey friend here is answer......

_____________________________

the perimeter of a square is 36 cm.

so,the length of each side of square=36/4=9 cm.

so the length of diagonal is =√( 9^2 + 9^2)
=√(2×81) = 9√2 cm
