Question

Find the area of a trapezium if its parallel sides are 12cm and 8cm and height is 5cm​

Answer 1

Answer:

Step-by-step explanation:

Area of trapizium=1/2(sum of llel side)×height of trapizium

Area=1/2×20cm×5cm

Area=50cm2 answer

Answer 2

Question:-

Find the area of a trapezium if its parallel sides are 12cm and 8cm and height is 5cm

Required Answer:-

Given:-

• Parallel sides of the trapezium = 12cm and 8cm
• Height of the trapezium = 5cm

To Find:-

• Area of the trapezium

Solution:-

First, we have to know that:-

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

Where,

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

Now,

Substituting the values:-

$\\ \sf{Area \: of \: the \: trapezium = \bold{ \frac{12cm + 8cm}{2} \times 5cm}}$

$\sf{\rightarrow{{Area \: of \: the \: trapezium = \bold{ (\frac{20}{2} \times 5) {cm}^{2} }}}}$

$\sf{\rightarrow{Area \: of \: the \: trapezium = \bold{ \red{50 {cm}^{2} }}}}$

$\\ \underline{\boxed{\rm{Hence, Area \: of \: the \: trapezium = \bold{50 {cm}^{2} }}}}$
