Question

the length of two parallel sides of a trapezium are 13cm and 8cm respectively and its height is 4cm, find its area.​

Answer 1

Question:-

The length of two parallel sides of a trapezium are 13cm and 8cm respectively and its height is 4cm, find its area.

Required Answer:-

Given:-

• Parallel sides of the trapezium = 13cm and 8cm
• Height of the trapezium = 4cm

To Find:-

• Area of the trapezium.

♡Solution:-

First,we have to know that;

$\\ \underline{ \boxed{ \pmb{area \: of \: a \: trapezium = \frac{a + b}{2} h \: sq.units}}}$

Where,

• a and b is the parallel sides of the trapezium
• h is the height of the trapezium

Therefore,

Substituting the values, we find:-

$\\ \sf{Area \: of \: the \: trapezium = \bold{ \frac{13cm + 8cm}{2} \times 4cm}}$

$\sf{ \rightarrow{{Area \: of \: the \: trapezium = \bold{ (\frac{21}{2} \times 4)cm {}^{2} }}}}$

$\sf{ \therefore{{Area \: of \: the \: trapezium = \bold{ \red{42cm {}^{2} }}}}}$

$\\ \\ \boxed{ \rm{ \green{Hence \: area \: of \: the \: trapezium \:is \: \bold{42 {cm}^{2} }}}}$

Answer 2

Answer:

hey what's up

beta particle, also called beta ray or beta radiation, is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay. There are two forms of beta decay, β⁻ decay and β⁺ decay, which produce electrons and positrons respectively.
