Afarmer needs to but fertilizer for two fields. one field is shaped like a triangle the other is shaped like a trapezoid. the trapezoid field has basis that are 35 and 48 yards and the height of 26 yards. the triangular field has the same height as th tr apezoidal field and a base of 39 yards. each bag of fertilizer covers 150 square yards. how many bags of fertilizer does the farmer have to

The farmer needs to buy 11 bags of fertilizer.

Given:
Trapezoid: bases 35 and 48 yards, height of 26 yards
Triangle: base 39 yards and height of 26 yards
1 bag of fertilizer covers 150 square yards.

Area of Trapezoid = (a + b)/2 * h
A = (35yd + 48yd)/2 * 26yd
A = 83yd/2 * 26yd
A = 41.50yd * 26yd
A = 1,079yd² 

Area of Triangle = (h*b)/2
A = (26yd * 39yd)/2
A = 1,014yd²/2
A = 507yd²

Total Area = 1,079yd² + 507yd²
T.A. = 1,586yd²

1,586yd² ÷ 150yd² = 10.57 or 11 BAGS OF FERTILIZER.
