Answer:
= 32.440
Step-by-step explanation:
Change the divisor 12.5 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.
We then have the equations:
4055 ÷ 125 = 32.440
and therefore:
405.5 ÷ 12.5 = 32.440
Both calculated to 3 decimal places.
HERE IS THE ANSWER (see the picture)
area=(b1+b2)*h all divided by 2
a=(12+12+8.7)*4.9 all divided by 2
a=32.7*4.9/2
a=160.23/2
a=80.12 sq. ft.
