Answer:
it is D hope this helps
Step-by-step explanation:
The length of AD is 75. Since opposite sides have the same length, 63 plus 63 is 126. The perimeter is 276, so 276 minus 126 is 150. 150 divided by 2 is 75.
Answer:
Step-by-step explanation:
I just answered this for someone else... here is the same answer I gave them
QR + RS +SQ = perimeter
2(XR) + 2(YS) + QS = perimeter ( b/c multiplication is communicative SQ=QS)
2*5 + 2 * 7 + 20 = perimeter
10 + 14 + 20 = p
44 = p
