Question

find the height of a trapezium whose area is 1080cm square and lengths of its parallel sides are 55.6cm and 34.4 cm

Answer 1

area=1/2h(a+b)
1080=1/2h(55.6+34.4)
1080=1/2h(90)
h=1080×2/90
h=108×2/9
h=12×2
h=24cm is answer

Answer 2

given area of trapezium = 1080 cm^2

1/ 2( sum of parallel sides )× h = 1080

1 / 2( 55 .6 + 34.4 ) × h = 1080

90h = 2160

h = 2160 / 90

h = 24 cm

hence ,the height of trapezium = 24cm
