Answer:
 Area of Trapezoid is 39 unit²
Step-by-step explanation:
Given as :
For A Trapezoid
The measure of base side 1 =  = 10 unit
 = 10 unit
The measure of base side 2 =  = 16 unit
 = 16 unit
The height of the Trapezoid = h = 3 unit
Let  The Area of Trapezoid = A square unit
<u>Now, From Formula</u>
Area of Trapezoid =  × (sum of opposite base) × height
 × (sum of opposite base) × height
I.e A =   × (
 × ( +
 +  ) × h
) × h
Or, A =   × (10 unit + 16 unit) × 3 unit
 × (10 unit + 16 unit) × 3 unit
Or, A =   × (26 unit) × 3 unit
 × (26 unit) × 3 unit
Or, A =   × 78 unit²
 × 78 unit²
Or, A =  unit²
 unit²
I.e A = 39 unit²
So, The Area of Trapezoid = A = 39 unit²
Hence, The Area of Trapezoid is 39 unit² . Answer
