The area of Mr. Dabo trapezium plot is 14300cm2. If the lengths of its parallel sides are 140cm and 80 cm respectively. Find its height.


The area of a trapezium (trapezoid) can be found using the formula:

\[
\text{Area} = \frac{1}{2} \times (a + b) \times h
\]

Where:
- \( a \) and \( b \) are the lengths of the parallel sides,
- \( h \) is the height,
- and the area is given.

Given:
- Area = 14300 cm²
- \( a = 140 \) cm
- \( b = 80 \) cm

We need to find the height \( h \).

Plugging the values into the formula:

\[
14300 = \frac{1}{2} \times (140 + 80) \times h
\]

Simplifying:

\[
14300 = \frac{1}{2} \times 220 \times h
\]

\[
14300 = 110 \times h
\]

Now, solve for \( h \):

\[
h = \frac{14300}{110} = 130 \, \text{cm}
\]

So, the height \( h \) of the trapezium is **130 cm**.
