Answer:
h = 4
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
• A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
h is the perpendicular height between the bases b₁ and b₂
given A = 28 , b₁ = 6 and b₂ = 8 , then
28 = [tex]\frac{1}{2}[/tex] h (6 + 8 ) ← multiply both sides by 2 to clear the fraction
56 = h × 14 = 14h ( divide both sides by 14 )
4 = h
The height of the trapezoid is 4 units
