Question

Mehraj wants to buy a trapezium shaped field its side along the river is parallel to and tortoise and the side along the road if the area of this field is 10500msq antiperspirant cooler distance between the two parallel side is 100 m find the length of the side along the river



​

Answer 1

Let side along the road be xm .

Side along the river = Twice of x

= 2x

Now,

Area of trapezium = 1/2 x ( sum of parallel sides) x height

10500 = 1/2 x ( sum of parallel sides) x

Height

10500 = 1/2 x (x+2x) x100

10500 = (3x) x 50

10500 = 150 x

10500 / 150 = x

70 = x

x =70

Side along the road = x = 70 m

and Side along the river = 2 x =

2 x 70 = 140 m

Answer 2

Answer:

here izz ur answer

Let the parallel sides of the trapezium-shaped field be

′

x

2x

′

m.

Let a=x and b=2x and h=100m

Then, its area.

=

2

1

(a+b)×hm

2

=

2

1

(x+2x)×100m

2

=50×3xm

2

=150xm

2

But it is given that the area of the field is 10500m

2

∴150x=10500

⇒x=

150

10500

=70

∴ The length of the side along the river is 2×70, i.e., 140m.
