Question

the area of a trapezium is 120 sq cm and the perpendicular distance between its parallel side is 8 cm.

Answer 1

area of trapezium=half×(sum of parallel sides)×height
let the height be x
120=1÷2(8)×x
x=30cm

Answer 2

area= 120sq.cm
height= 8cm
area= 1/2(a+b) ×h
120=1/2(a+b)×8
(a+b)=(120×2)/8
(a+b)=30cm
