The area of a trapezium-shaped field is 30 m2, and the distance between its parallel sides is 6 m. Find the measure of parallel sides of the field if the difference in their measurements is 2 m.

Answer:

Measurements of the parallel sides are 4m , 6m.

Step-by-step explanation:

Area of trapezium:

[tex]\boxed{\text{\bf Area of trapezium =$\bf \dfrac{(a + b)*h}{2}$}}[/tex]

Here, a and b are the measurements of the parallel sides.

h denotes height. h = 6 m

Area = 30 square m

It is given that the difference in the measurements of parallel sides is 2m.

  If we take measure of one parallel side is 'x', then the measure of the other parallel side = x +2

a = x and b = x +2

       [tex]\sf \dfrac{(x + x + 2)*6}{2}= 30\\\\\\ \dfrac{(2x +2)*6}{2}=30[/tex]

        (2x + 2)*3 =30

     Divide both sides by 3,

           2x + 2 = 30 ÷ 3

           2x + 2 = 10

    Subtract 2 from both sides,

                    2x = 10 - 2

                    2x = 8

     Divide both sides by 2,

                       x = 8 ÷ 2

                       x = 4

a = 4 m

b = x + 2

  = 4 + 2

  = 6 m

Measurements of the parallel sides are 4m, 6m.
