Question

If the lengths of 2 parallel sides of
trapezium are 7cm and 13 cm
respectively, height is 4 cm then the
area of trapezium is
​

Answer 1

Solution:

• Here,The length of two parallel sides of trapezium are 7 cm and 13 cm and height of trapezium is 4 cm,so that we can use the formula of area of trapezium to find the answer of area of trapezium.

Let's do it,

____________________________

Required Formula:-

$\\ \green{\bigstar}\;\underline{\boxed{\sf{Area\;of\;trapezium\;=\;\frac{1}{2}(a+b)h}}}$

Therefore,

$\\ \twoheadrightarrow\;\sf{Area\;of\;trapezium\;=\;\frac{1}{2}\times (7+13)\times 4}\\ \\ \\ \twoheadrightarrow\sf\;{Area\;of\;trapezium\;=\;\frac{1}{2}\times 20\times 4}\\ \\ \\ \twoheadrightarrow\sf\;{Area\;of\;trapezium\;=\;\frac{1}{\cancel{2}}\times \cancel{80}}\\ \\ \\ \twoheadrightarrow\;\underline{\boxed{\frak{Area\;of\;trapezium\;=\;40\;cm}}}\;\red{\bigstar}$

Hence,

• The area of trapezium is 40 cm.
