Question

Find the area of this following trapezium,~
Figure in Attachment
~​

Answer 1

Step-by-step explanation:

Area of trapezium= 1/2(sum of parallel sides)× height

so,

height is 3cm, parallel sides are 7cm and 9cm

A to Q

1/2(7+9)×3

1/2×16×3

16 is divided by 2 to 8 times so

8×3= 24

Area of trapezium= 24cm

Answer 2

Question

• Find the area of this following trapezium
• Figure in Attachment

Solution

~ Formula Used :

$\huge{ \maltese{ \boxed{ \sf{ \large{ \pink{ \frac{h(a+b)}{2}}}}}}}$

${ \underline{ \underline{ \rm{ \large{Let's \: Start}}}}}$

${ \longmapsto{ \rm{ \dfrac{3(7 + 9)}{2}}}}$

${ \longmapsto{ \rm{ \dfrac{3(16)}{2}}}}$

${ \longmapsto{ \rm{ \dfrac{48}{2}}}}$

${ \longmapsto{ \rm{ \cancel \dfrac{48}{2}}}}$

${ \rm{ = 24cm {}^{2} }}$

${ \large{ \bf{ \pink{ = 24cm {}^{2} }}}}$

${ \underline{ \underline{ \frak{Therefore,}}}}$

" Area of Trapezium=24cm^2 "

${ \rule9cm0.2cm}$

Additional Information

${ \boxed{ \rm \green{Area \small_{ (\triangle)Triangle} = \dfrac{1}{2} \times b \times h }}}$

${ \boxed{ \rm \blue{Area \small_{(Parrellelogram) } = b \times h }}}$
