Step-by-step explanation:
\huge{\boxed{\boxed{\tt \red{G}\green{i}\pink{v}\orange{e}\purple{n}:}}}
Given:
The parallel sides of a trapezium are 28.7 cm and 22.3 cm
The distance between the parallel sides (i.e. altitude/height) is 16 cm
\huge{\boxed{\boxed{\tt \red{T}\green{o}\ \pink{Fi}\orange{nd}\purple{:}}}}
To Find:
The area of the trapezium.
The formula to find the area of a trapezium is
\boxed{\bf{=\frac{1}{2}\times (sum\ of\ parallel\ sides) \times altitude}}\: units\ sq.
=
2
1
×(sum of parallel sides)×altitude
units sq.
The area of the trapezium is
= \frac{1}{2} \times (28.7 + 22.3) \times 16=
2
1
×(28.7+22.3)×16
[Sum of parallel sides, (28.7+22.3 = 51)]
And
[16 ÷ 2 = 8]
= 51 × 8
= 408 cm sq.
Hence,
The area of the trapezium is 408 cm sq.
