In triangle xyz, the length of side xy is 21 mm and the length of side yz is 31 mm. which of the following could
be the length of side xz?

There are two possible answer answer is this problem since no diagram is given

First if XZ is the longest side

XZ < Xy + YZ

XZ < 31 + 21

The possible length of XZ = 51 mm

If XZ is not the longest length

YZ < XZ + XY

31 < 21 + XZ

So the possible length of XZ = 11 mm

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing
