Question

geometry

Answer 1

area of a square = length x length square units
so l^2 = 25 square cm or l = 5 cm
now each triangle is right angled triangle with sides 5 cm
so the hypotenuse can be found by pythagoras theorem hypotenuse = sqrt [ base^2+ perpendicular ^2] or h = sqrt [5^2+5^2]

Answer 2

Ok. I think that gave me the hang of it, thank you so much!

Answer 3

a right angled triangle has 3 sides base, perpendicular and hypotenuse in this case base= perpendicular and they are sides of the same square !!
