1) It is a 6 × 9 rectangle, so the area is 6 9 = 54 i n 2
2) It is a 4 × 4 square so the perimeter is 16in
3) 112/8 = 14 so the height of the triangle is 14m
4) The rectangle with the greatest area is a square, so itwould be a 10 × 10 square with a area of 100cm
5) It is a 5 × 7 rectange, so the area is 5 7 = 35 i n 2

1. let x be witdth
3+x=length
P=2L+2W,
2x+2(x+3)=30
4x+6=30, x=6 inches width
3+x=3+6=9 inches length
A = l w = 9 ( 6 ) = 54 i n 2
2. A = x 2 , 16 = x 2 , x = 4 y d
P=4s=4(4)=16yd
3. area triangle
A = 1 2 b h , 112 = 1 2 ( 16 ) h
224=16h, h=14m
4.P=2l+2w,40=2l+2w,
l+w=20, l=20-w
A = l w = ( 20 w ) w = 20 w w 2
find vertex
w = b 2 a = 20 2 = 10
A ( 10 ) = 20 ( 10 ) 10 2 = 200 100 = 100 c m 2
5. let x be width
2+x = length
p=2l+2w, 24=2(2+x)+2x
2x+2x+4=24, 4x=20, x=5 in width
length 2+x=2+5=7in
now area
A = 7 ( 5 ) = 35 i n 2

Given a right triangle A B C rotated 2 π, one full circle, around line B C. Find area of the formed cone.
Everyone knows that the formula for a cone includes a 1 3 in it due to some integral calculus.
Why can the area of a cone not be visualized as a triangle rotated about an axis? Intuitively this makes sense. The area of a triangle is 1 2 b h. The distance it is rotated is 2 π. By that this should give us a formula b h π. This seems to work for a cone with r = 3 and height 4.

Determine whether the two triangles are similar.
Explain
1. The two triangles are not similar. Since mBmF, the triangles are not similar by the AA criterion.
2. The two triangles are similar. By the Interior angles theorom, mC=67, so the triangles are similar by the AA criterion.
3. The two triangles are similar. By the interior angles theorem, mc=57, so the triangles are similar by the AA similarity criterion.
