Answer to Problem 8.2.7P
Explanation of Solution
Given information:
An enclosed area.
Formula used:
Area of rectangle=
Calculation:
To find the area, divide the area into sub-areas and add the areas of the figure of together.
Solving rectangle with length 6s - 1 and breadth s
Substituting values in formula,
Area=
Multiplying,
Area=
(1)
Again, solving area with length 5s and breadth 4s (breadth= 4s because 6s -1-( 2s -1) = 4)
Substituting values in formula,
Area=
Solving,
Area=
So,
Area=
(2)
Now, solving area with length 2s and breadth s +2
Substituting values in formula,
Area=
Solving,
Area=
So,
Area=
(3)
Adding (1), (2) and (3)
Area=
Adding like terms,
Area=
Hence, total area of the shape is
