Ik this is not what you were looking for but what kind of problem is this lol. i never seen this
H = 12f
h = height of the building in feet
f = number of floors
Answer:
100 m^2.
Step-by-step explanation:
The area of a trapezoid = (h/2) (a + b) where h = the perpendicular distance between the 2 parallel sides and a and b are the lengths of the 2 parallel sides.
Here we have Area = (1/2 * 10) ( 8 + 12)
= 5 * 20
= 100 m^2.
The answer is 838.09528(09528 has a line above it)
The missing side of the fence measures 15 ft
The perimeter of the fence is 40 ft
The area inside the fenced in section is 60 ft²
The fence is triangular and a right triangle.
<h3>Right triangle:</h3>
A right triangle has one of its angle as 90 degrees. Therefore, the sides can be found using Pythagoras theorem.
c² = a² + b²
17² - 8² = b²
b = 15 ft
AC = 15 ft
perimeter of the triangle = 15 + 8 + 17 = 40 ft
Area of the triangle = 1 / 2 × 15 × 8 = 60 ft²
Therefore,
The missing side of the fence measures 15 ft
The perimeter of the fence is 40 ft
The area inside the fenced in section is 60 ft²
