Answer:
≥ 34 feets
Step-by-step explanation:
Given that :
Height of triangle, h = 14 feets
Area of triangle is atleast 238ft²
Area of triangle formula, A :
Area = 0.5 * base * height
For an area of atleast 238ft²
238ft² = 0.5 * b * 14
238ft² = 7b
b = 238ft² / 7 ft
b = 34 ft
Hence, length of base needs to be 34 feets or higher
