Answer:
31.5cm²
Step-by-step explanation:
area of a triangle =1/2 b h
b= 7cm
h=9cm
1/2×7×9
= 1/2×63
= 31.5cm²
hypotenuse is unknown so,
c²=a²+b²
c²= 7² + 9²
= 49 + 81
c²= 130
c= 11.4cm
perimeter= 7 +9+11.4
=27.4cm
pls note that no unit was stated
Answer:
That incorrect
Step-by-step explanation:
Yes
You can test this using the equation: a^2 + b^2 = c^2.
24^2 + b^2 = 60^2
576 + b^2 = 3,600
b^2 = 3,024
b = 54.999
Since b is not a whole number, the side lengths do not form a Pythagorean triple.
