Answer:
y = 7
NO = 5
Step-by-step explanation:
Let the side of the parallelogram LM and NO given be 2y - 9 and y - 2
Since LMNO is a parallelogram, hence;
LM = NO
2y - 9 = y - 2
2y - y = -2 + 9
y = 7
Since NO = y - 2
NO = 7 - 2
NO = 5
You always have to find the LSA (lateral surface area) first.
(which is the shape's area combined w/out the bases.)
rectangle A would be 60 and so would rectangle C
rectangle B would be 96
if u add them all together that would be 12.5
Now you have to find the TSA (total surface area).
(which is the TOTAL net combined w/ bases)
the bases would be 7.5
7.5 x 2 is 12.5
Add the LSA and the TSA
216+12.5=228.5
<u>so the overall answer would be 228.5cm</u>
i hope this helps!!
I would say that the answer is true
Answer:
12 x 9 = 108
Step-by-step explanation:
Just multiply the 2 given lengths when finding AREA of a rectangle.
