Answer:
approximately 6.7
Step-by-step explanation:
I'm assuming this is a triangle, but since there's no picture that's just my guess
We can use The Pythagorean Theorem
3•3=9
6•6=36
9+36=45
square root of 45 is approximately 6.7
Answer:
18 cm for area or perimeter, or just multiplying if y= 3cm*6cm
Step-by-step explanation:
For Perimeter:
multiply 3 by 2, and get 6, then multiply 6 by 2 and get 12 then you will add 6 and 12 together to get 18
For Area:
multiply 6 by 3 or do 6+6+6 and get 18 either way
For Multipling to find y:
do the same that you would do for finding the area
