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.

You can work this out in the straight-forward way, or you can recognize that (6-i) is a common factor. In the latter case, you have ...
... = (6-i)(5 + 3-i)
... = (6 -i)(8 -i)
This product of binomials is found in the usual way. Each term of one factor is multiplied by each term of the other factor and the results summed. Of course, i = √-1, so i² = -1.
... = 6·8 -6i -8i +i²
... = 48 -14i -1
