Answer:
i had this on my last year book
lemme see if i can find it
Answer: B.
Explanation:
Consider any right triangle that has both its legs of same length. In this case both the other two angles would be 45 degrees each. Now, if both its legs are considered of unit length, then hypotenuse would be of length √2.
The cos 45 = 1/√ 2 = √ 2/2
Hope this helped! :)
2l + 2w = 344
2(3w+8)+2w = 344
6w+16+2w=344
8w=328
width=41
Then plug back into the perimeter equation
2l + 2(41)=344
2l + 82 = 344
2l= 262
length=131
