Answer: 24 square units
Explanation:
The Area of a trapezoid is:
1/2 (a + b) h
Where ;
a = Length of base 1
b = length of base 2
h = height of trapezium
From the diagram attached :
a = Length of BC =(-1 to 3) =4units
b = length of AD =(-3 to 5) = 8 units
h = (-2 to 2) = 4 units
Plugging the values :
Area = 1/2 ((4 + 8)2)
Area = 0.5 × (12) × 4 = 12
Area = 6 × 4 = 24square units
