No, the answer is 2
X=2
This is because if we multiply the number by x which is 2
so DST is 110, and RSD is 44, so that is 154, and if we do it with RST we also get 154
So the correct answer is X=2
A=l*w
161=14w
161/14=w
11.5cm is the width
-- The area of the long skinny piece on top is (6 x 33) = 198
-- The length of the dotted line between the top and bottom pieces is (33-21) = 12
-- The area of the bottom piece is (12 x 15) = 180
-- The area of the whole thing is (198 + 180) = 378
-- The perimeter of the whole thing is (33 + 6 + 21 + 15 + 12 + 15 + 6) = 108
The third one down is the correct answer. (-55 and 1)
