Question

the area of a trapezium is 2500m square. one of it's parallel sides is 75m. if the distance between the two parallel sides is 40m. find the other parallel side

Answer 1

Let the other parallel side be x.

Area of trapezium=1/2*sum of parallel sides*height

=>2500=1/2*(75+x)*40

=>2500=20(75+x)

=>x=(2500-1500)/20

=>x=50

So,the other parallel side is 50m.

Answer 2

The other parallel side is 50 m

Step-by-step explanation:

Let the other parallel side be x

One of parallel side = 75 m

Distance between parallel lines = 40 m

Area of trapezium = $\frac{1}{2} (\text{Sum of parallel sides }) \times height$

Area of trapezium =$\frac{1}{2} (75+x) \times 40$

The area of a trapezium is 2500m square.

$\frac{1}{2} (75+x) \times 40 = 2500$

$75+x=\frac{2500 \times 2}{40}$

75+x=125

x=125-75

x=50

Hence the other parallel side is 50 m
