Answer:

Step-by-step explanation:

they are just trying to trick you... by giving you 1/2 of some of the sides and then the whole side on the last one

QR + RS + QS = perimeter

2(XR) + 2(YS) + QS = perimeter

2(5) + 2(7) + 20 = perimeter

10 + 14 + 20 = perimeter

44 = perimeter :)

Answer:

The perimeter is 44. Because we know the midpoints and distance between the sides of XR is half the side and YS is half the other side, those sides are 10 and 14. QS is a full side already so it is just 20. 20+14+10=44 for the perimeter.

Number 2 makes no sense, you've omitted something needed there.

we just need the legnth of the rectangle which is the circumfernece of the circle

C=pid
d=12
C=12pi

area=lw
aera=12pi*15
