Answer:
The are of QRSTU is 65 square units
B is correct.
Step-by-step explanation:
Please see the attachment for figure QRSTU
Q is at (3,0)
R is at (-3,0)
S is at (-3,7)
T is at (1,11)
U is at (5,7)
First we make three triangle. Join SQ and QT
We get three triangle
ΔSRQ, ΔSQT and ΔTQU
Area of triangle formula
Area of QRSTU = ar(ΔSRQ) + ar(ΔSQT) + ar(ΔTQU)
Area of QRSTU = 21 + 26 + 18
= 65 square unit
Hence, The are of QRSTU is 65 square units
The correct answer is 65 square units!! :)

Step-by-step explanation:
My answer is wrong sorry. I didn't notice it.
1 3/8 the denominators have to be the same so you multiply 2 to 3/4 to get 6/8 btw they are common denominators so you can easily multiply two and the you add the to get 11/8 and if you simplify it you'll get 1 3/8
