Question

3. The area of a trapezium shaped field is 3,400 m² and the length of one of the parallel
sides is 100 m and its height 40 m. Find the length of other parallel sides.​

Answer 1

Step-by-step explanation:

let the length of other parallel side be x

Area of trapezium = 3,400 m^2

height ( h ) = 40m

length of one parallel side = 100m

Area of trapezium = 1/2(sum of parallel sides)×h

3,400 = 1/2( 100+x) × 40

3,400 ×2 = (100+x)×40

6,800 /40 =100+x

170 - 100 = x

70 = x

Answer- the length of other parallel side is 70m.

Answer 2

Answer:

let the length of other parallel side be x
