Step-by-step explanation:
Circumference (C):

Area (A):

The base must be perpendicular to the height for area= bh/2.
We can use RS as the base and TU as the height.
6*3/2
18/2
9
Final answer: 9 units^2
Answer:
$10.32
Step-by-step explanation:
6.45/ 5 = 1.29
1.29 * 8 = 10.32
Answer:
x = - 
Step-by-step explanation:
A theorem states that (using letters from in this problem) that:
AB * BE = DC * CE
Applying that you can find that:
11 ( x + 1 ) = 1 ( x + 4 )
11 x + 11 = x + 4
11 x + 11 - x = x + 4 - x
10 x + 11 = 4
10 x + 11 - 11 = 4 - 11
10 x = -7
10 x / 10 = -7 / 10
x = -
