Answer 1

Step-by-step explanation:

firstly we have to find its side by phytagoras thereom.

as we know a square is build up of two triangles.

hypoteneus side sq. is 10

base ?

perpendicular ?

10 sq. = x sq. + x sq. (sq. cancel)

10 = x + x

10=2x

2x=10

x = 10 ÷ 2

{x = 5.}

side = 5

perimeter = 4 x s

= 4 x 5

=20

Answer 2

20 is your answer think so.
