The area is the area of 2 pairs of congruent triangles and one rectangle. Use the formulas for the areas of these figures, then add results.
Front triangle area (A = (1/2)bh)
.. = (1/2)(16 m)*(25 m) = 200 m^2
Right side triangle
.. = (1/2)(22 m)*(24 m) = 264 m^2
Base (A = lw)
.. = (16 m)*(22 m) = 352 m^2
Total area
.. 2*front triangle +2*side triangle +base
.. = 2*200 m^2 +2*264 m^2 +352 m^2
.. = 1280 m^2
Answer:
Find the 40th term for the arithmetic sequence in which
a8=60 and a12=48 .
Substitute 60 for a8 and 48 for a12 in the formula
an=a1+(n−1)d to obtain a system of linear equations in terms of a1 and d .
a8=a1+(8−1)d→60=a1+7da12=a1+(12−1)d→48=a1+11d
Subtract the second equation from the first equation and solve for d .
12=−4d−3=d
Then 60=a1+7(−3) . Solve for a .
60=a1−2181=a1
Now use the formula to find a40 .
a40=81+39(−3)=81−117=−36 .
