Answer 1

Answer: 40 sq. cm

Step-by-step explanation:

Given: Parallel sides= 10 cm and 12 cm

Height= 4 cm

By using the given formule,

Area of Trapezium= 1/2*sum of parallel sides*height

we get,

Area of Trapezium=1/2*(10+12)*4 sq. cm

                               =1/2*22*4 sq. cm

                               =22*2 sq. cm [by dividing 2 by 4]

                               =44 sq. cm
