What is the area of the trapezoid? If necessary, round your answer to the nearest tenth.
1 answer:
The area of the trapezoid is calculated as 45.5 feet squared.
<h3></h3>What does Area of Trapezoid mean?
The entire area occupied by the sides of a trapezoid is its area. It's important to notice that if we know the lengths of all the sides, we can divide the trapezoid into smaller polygons, such as triangles and rectangles, calculate their areas, and then sum them all together to determine the area of the trapezoid.
<h3>The formula for Trapezoid Area:</h3>If the parallel sides of the trapezoid are known, along with their height, it is possible to determine their area. It is expressed as,
A=(a+b) h
where, A= the area of the trapezoid
h= height
'a' & 'b' = parallel side bases
<h3>Solution:</h3>a=5.5 feet , b= 8.5 feet & h=6.5 feet
A=(a+b)h
∴A=(5.5+8.5)*6.5
⇒A=(14)*6.5
⇒A=7*6.5
⇒A=45.5 feet squared
Therefore, the solution is (b) 45.5 feet squared.

<u>Arithmetic Sequences </u>
The arithmetic sequences are those where any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.
The equation to calculate the nth term of an arithmetic sequence is:
Where
an = nth term
a1 = first term
r = common difference
n = number of the term
We are given the arithmetic sequence:
10, 12, 14, 16, ...
Where a1=10 and
r = 12 - 10 = 2
Thus the general term is:
