A square has a side of 5 ft. What is<br> the perimeter of the triangle?

luda_lava [24]

I'll draw it for you cause im nice.

Ok so if you have 5ft on a square, all the sides are 5ft.

That mean that if its in half, one of the sides will be 2.5ft.

Now you can add 2.5 + 2.5 + 5+5 = 15.

So its 15 ft.

Rasek [7]

6.5c + 9.7a = 1721.4
a = 4c

6.5c + 9.7(4c) = 1721.4
6.5c + 38.8c = 1721.4
45.3c = 1721.4
c = 1721.4 / 45.3
c = 38...so there were 38 childrens' tickets <==
and 152 adult tickets
