Answer to Problem 22E
The area of region bounded by straight lines is approximated by breaking it into regular polygons and use the formulas for the area of regular polygons and the area for the polygon with boundary curved is evaluated by drawing the rectangles below the curve and with the help of area of rectangle sum the area of the curve.
Explanation of Solution
For the area of the region bounded by straight lines, break the polygon into regular polygons.
Then use the area formulas of regular polygons and sum all the areas of regular poylgons.
This gives the area of the region bounded by straight lines.
For the area of the region bounded by curve, draw the rectangle in the area under the curve with equal length and breadth.
Then calculate the area of all the rectangles.
Then decrease the width of the rectangles as much as possible to reduce the area which is extra.
At last this will give the approximate area of the region bounded by the curves.
