Question 979945: Not able to follow the formula for solving this problem. Can you help me?
Find the area of the front face of a blade. The expression 1/2h(b + D) gives the area of the trapezoid.
d =1 1/4
h =3/4
b =2 3/8

You can put this solution on YOUR website!
area=(1/2)h(b+d)
I assume the measurements are in inches, so the area would be in square inches.
d+=1%261%2F4=1%2B1%2F4=4%2F4%2B1%2F4=5%2F4 or d+=1%261%2F4=1%2B1%2F4=1%2B0.25=1.25
h+=3%2F4=0.75
b+=2%263%2F8=2%2B3%2F8=2%288%2F8%29%2B3%2F8=16%2F8%2B3%2F8=19%2F8 or b+=2%263%2F8=2%2B3%2F8=2%2B0.375=2.375

You could use the measurements as fractions or as decimals.
Either way, a calculator would be very helpful.
