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
