Question:-

  • If the area of a trapezoid is 25 cm and the parallel sides are 8 cm and 12 cm respectively, what is the length of the parallel sides?

To Find:-

  • Find the length.

Solution:-

Given ,

  • Area is 25 cm

  • Parallel sides area 8 cm and 12 cm.

Now ,

We have to find the height:-

\sf\longrightarrow \: A = \dfrac { 1 } { 2 } ( a + b )  h

\sf\longrightarrow \: 25 \times 2 = ( 8 + 12 )h

\sf\longrightarrow \: 50 = 20h

\sf\longrightarrow \: h = \cancel\dfrac { 50 } { 20 }

\sf\longrightarrow \: h = 2.5

Hence ,

  • Height is 2.5 cm
