Answer 1

An isosceles right triangle means

perpendicular side = base side = x

area of right triangle = (½)*base*perpendicular= 200

putting in formula,

½* x*x = (½)x² = 200

x² = 400

x=✓400

x= 20cm

perpendicular=base=20cm

now by applying Pythagoras theorem,

(hypotenuse)² = (base)² + (perpendicular)²


putting values in formula we get,

(h)²= (20)²+(20)²

(h)² = 400+400

h²= 800

h=✓800

h= 20✓2cm

hypotenuse=20✓2cm

hope this helps you
