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

Answer:
Step-by-ste
Oh, oh! This is such a tricky question...
Guess what!
Both of them are correct. Why?
Because if we simplify 3/12, we get 1/4th!
(How do you simplify?)
3/12 = 1/4
Because if we divide both "3" and "12" in 3/12 by 3, we get 1 instead of 3 and 4 instead of 12.
I hope you've got it! ;)
