Answer:
Step-by-step explanation:
HEY!!
Areas of trapezium = 540 cm^2
height = 18 cm
it's parallel side ratio 7:5
let the 1 ratio be 7x
let the 2 ratio be 5x
area of trapezium = 2h (sum of parallel side )
540 =2×18 ×(7x +5x)
540 / 18 ×2 = 12x
60 = 12x
60 / 12 = x
5 = x
so it's parallel side 7x = 7× 5 =35
and 2 parallel side 5x = 5 ×5 =25

hey
_______________
•area of trap = sum of || sides× height
let sides be 7x and 5x
540 = 1/2 ( 7x+5x)×18
540=1/2×12x×18
540/108 = x
x=5
sides are 7×5 =35 cm and 5×5=25cm
hope helped
