The area of trapezium shaped field is 540msquare, if the ratio of parallel sides is 7:5 and the distance between them is 18 cm. Find the length of parallel sides.
• please check up the units carefully.., area is in msquare and distance is in cm.
SanyaBhasin:
ok thanks
chainednomad can u solve again i m not able to find up your answer
please
Isn't it 3500,2500 ?
my answer is coming 2000
that's why i put it here
it can be wrong as well
Applying in the formula: A = 1/2 * [3500+2500]*18/100 = 1/2 * 6000 * 18/100 = 1*6000*18/200 = 30*18=540 m^2.. verified.
thank u so much

Answer: 3500m, 2500m
Step-by-step explanation:
Area of Trapezium = 1/2 * (sum of parallel sides) * distance between them
Area = 540 m^2
Distance = 18 cm = 18/100 m
Ratio of parallel sides = 7:5 == 7X,5X
540 = 1/2 *(7X + 5X)*18/100
540*2*100/18 = 12X
6000 = 12X
X = 6000/12 = 500
Hence length of parallel sides = 7X , 5X = 7*500, 5*500
= 3500 m , 2500 m
