Answer:219.96 yd²
Explanation:The area of the trapezoid can be calculated using the following rule:Area of trapezoid =

where:
b1 is the length of the first base
b2 is the length of the second base
h is the height
Now, in the given we have:b1 = 15.8 yd
b2 = 21.8 yd
h = 11.7 yd
Substitute with the givens in the above equation to get the area as follows:area =

Hope this helps :)

and works for any triangle.
Therefore, we have the proportion:

Answer:
Step-by-step explanation:1 over 4 and divide 6.2 divided by the one and the 1 and 4
Answer:
k = 
Step-by-step explanation:
Using the rules of logarithms
log x - log y = log(
)
log a = log b ⇒ a = b
Given
logk - log(k - 2) = log25, then
log (
) = log25, thus
= 25 ( multiply both sides by (k - 2)
25(k - 2) = k
25k - 50 = k ( subtract k from both sides )
24k - 50 = 0 ( add 50 to both sides )
24k = 50 ( divide both sides by 24 )
k =
=
