Answer 1

Answer:

h = 16 cm

Step-by-step explanation:

area of trapezium= (Sum of parallel sides /2)×h

120 = (7 +8/2)×h

120 = 15/2 × h

120= 7.5× h

h =120/7.5

h = 1200/ 75

h= 16 cm

Answer 2

LET THE HEIGHT BE X CM .

AREA OF THE TRAPEZIUM = 120 CM² .

PARALLEL SIDES = 7CM , 8CM .

SO,

[ 1/2 × ( 7 + 8 ) × X ] = 120CM² .

=> ( 1/2 × 15X ) = 120CM²

=> 16CM is your answer
