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
