Question

The area of a Trapezium is 105 CM square and its height is 7 cm if one of the parallel side is longer than the other by 6 cm find the length of the two parallel side?

Answer 1

area of trapezium= h(a+b)/2
given, area=105cm^2,h=7cm,a=x cm,b=(x+6)cm
therefore, 105=7(x+x+6)/2
=>2x =24=>x=12
req. lengths are a=12, b=12+6=18
