The area of trapezium is 540 cm2 and the altitude is 18cm. If one of the parallel sides is 12cm longer than the other. Find the length of
both the parallel sides.
Area = 540 cm
Altitude = 18cm
Let one parallel side be x cm and other be (x + 12)cm
According to qu.
1/2 × (sum of parallel sides) × h = 540
1/2 × (x + x + 12) × 18 = 540
2x + 12 × 9 = 540
2x + 12 = 540/9
2x + 12 = 60
2x = 60-12
2x = 48
x = 24 cm
.°. One side = 24cm
Other side = 36cm
Answer:
Area = 540 cm
Altitude = 18cm
Let one parallel side be x cm and other be (x + 12)cm
According to Questions:
1/2 × (sum of parallel sides) × h = 540
1/2 × (sum of parallel sides) × h = 5401/2 × (x + x + 12) × 18 = 540
=> 2x + 12 × 9 = 540
=> 2x + 12 = 540/9
=> 2x + 12 = 60
=> 2x = 60-12
=> 2x = 48
=> x = 24 cm
One side = 24cm
Other side = 36cm
