given
one side = 7x
two side = 5x
area = 540 cm
area of trapezium = 1/2 × sum of parallel side × height
= 1/2×7x +5x ×18
1/2× 12x × 18
now you can do i think i am sorry i am not done it full if you have doubt please tell me

Let the first parallel side= 7x
Let the second parallel side=5x
height=18cm
area of trapezium = 1/2 (sum of its parallel sides)×height
540cm=1/2×(7x+5x)×18
540=108x
540/108=x
3=X
length of 1st parallel side=7x =7×3=21
length of 2nd parallel side=5x=5×3=15 if it helps you pleazzzz mark as brainliest
