A = 5 / 2 a^2 square root over 5 + 2 square root of 5
hopefully this helps you out
For a width of 25, the length will also be 25, so the area is 25² = ...
625.
_____
The rule is
area = width×(50 -width)
Ok so, 42 ft. by 42 ft.
$25 per square yard
1 square yard = 9 square feet
The total square footage is 1,764 ft.
Total square yards is 196.
The total cost would be $4,900.
Answer:
Pretty sure it's 20.24.
Step-by-step explanation:
Since you know the side adjacent to the reference angle and you want to find the side opposite, you're going to need to use tangent, which is opp/adj.
tan(39) = 
Find the tangent of 39...
0.8097 is the approximate value. So...
0.8097 = 
Now, switch the sides to make it easier.
= 0.8097
Multiply both sides by 25.
x = 20.24
