From the given diagram note that, the dove tail is in the shape of a parallelogram. It is known that, area of a parallelogram is A=12(a+b)h where a and b are the length of the opposite sides of the parallelogram and h is the height of the parallelogram. Calculate the value of a and b from the figure as follows. a=17.90-5.20-5.20a=7.50 cmb=17.90-3.40-3.40b=11.10 cm Now, calculate the height of the parallelogram as shown below. h=6.40-4.20h=2.20 cmSubstitute the obtained values of a, b and h in the equation for area and calculate the area value as follows. A=12(a+b)hA=12(11.10+7.50)2.20A=20.46 cm2A=20.5 cm2 Thus, the cross sectional area of the dovetail is 20.5 cm2.
