Question

Find the area of a trapezium whose parallel sides are 57 cm and 33 cm and the
distance between them is 13 cm.

​

Answer 1

Step-by-step explanation:

it is step by step instructions

Answer 2

$\frak{Given}\begin{cases} \sf{The \:Distance \:between \:\parallel \:or\:Height \:is\:13cm\:}\\\sf{The\:Parallel \:Sides\:of\:Trapezium \:are\:57cm\& 33 cm}\end{cases}$

Need to find: The Area of Trapezium.

⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━

❍ The Formula for Area of Trapezium is given by :

⠀⠀⠀$\dag\;{\underline{\frak{As\;we\;know\;that,}}}$

$\star\;{\boxed{\sf{\pink{Area_{\;(trapezium)} = \dfrac{1}{2} \times (a + b) \times h}}}}$

Where,

• a and b are the two parallel sides and h is distance between two parallel sides or height of trapezium.⠀⠀⠀⠀

$\dag\;{\underline{\frak{Now,\: Substituting\:values\:in\;formula,}}}$

$:\implies\sf \dfrac{1}{2}(57 + 33) \times 13 \\\\\\:\implies\sf \dfrac{1}{\cancel {2}} (57 + 33 )\times \cancel {13}\\\\\\:\implies\sf (57 + 33) \times 6.5 \\\\\\:\implies\sf 90\times 6.5 \\\\\\:\implies{\underline{\boxed{\frak{\pink{Area = 585\;cm^{2}}}}}}\;\bigstar$

$\therefore{\underline{\sf{Hence, \;the\;Area\;of\: Trapezium \;\;is\;\bf{ 585\;cm^2}.}}}.$
