Question

Two parallel sides of a trapezium are 60cm and 77 cm and other sides are 25 cm and 26 cm find the area of the trapezium

Answer 1

hii

Area of parallelogram    = 2 × Area of ∆ABC 

                                   = 2 × 1/2 × base × height sq. units 

                                   = 2 × 1/2 × AB × CE sq. units 

                                   = b × h sq. units 

                                   = base × height sq. units 

Perimeter of parallelogram = 2(AB + BC) 

                                       = 2 × (Sum of adjacent sides)
