Perimeter and legs

Determine the perimeter of a right triangle if the length of one leg is 75%, the length of the second leg, and its area is 24 cm2.

Correct answer:

o =  24 cm

Step-by-step explanation:

r=75%=10075=43=0.75 S=24 cm2  b = r a  S = 2ab 2S = a r a  a=r2 S=0.752 24=8 cm  b=r a=0.75 8=6 cm  c=a2+b2=82+62=10 cm  o=a+b+c=8+6+10=24 cm
