Ayouth group is setting up camp. rain is predicted, so the campers decided to build a fly, or rain cover, over their tent. the fly will be 12 feet high and 16 feet wide. the scouts are building the frame for the fly with two poles slanted and joined together at the top of the tent the minimum length of the slanted piles needed to support the fly feet.

14.422 feet

Step-by-step explanation:

The campers decided to build a fly, or rain cover, over their tent.

The fly will be 12 feet high and 16 feet wide.

Refer the attached figure

AD =12 feet

BC = 16 feet

The fly is in the shape of cone we take cut section of it in the form of triangle.

So, the triangle is isosceles triangle .

Since AD is the perpendicular bisector of the isosceles triangle .So, BD = DC

So, D is the midpoint of BC

So, BD= DC=

BD= DC=

BD= DC= 8

So, we will use Pythagoras theorem in ΔADC

The minimum length of the slanted piles needed to support the fly is 14.422 feet.

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
