Question

help me solve Q3 a and b part answer with explanation plzzz.

Answer 1

Q3.(a)

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\green{\tt{\therefore{Height\:of\:parallelogram=9\:cm}}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\green{\underline \bold{Given :}} \\ \tt: \implies Area \: of \: parallelogram = 144 \: {cm}^{2} \\ \\ \tt: \implies Base \: of \: parallelogram = 16 \: cm \\ \\ \red{\underline \bold{To \: Find :}} \\ \tt: \implies Height \: of \: parallelogram = ?$

• According to given question :

$\bold{As \: we \: know \: that} \\ \tt: \implies Area \: of \: parallelogram = b \times h \\ \\ \tt: \implies 144 = 16 \times x \\ \\ \tt: \implies \frac{144}{16} = x \\ \\ \green{\tt: \implies x = 9 \: cm}$

Q3.(b)

$\blue{\bold{\underline{\underline{Answer:}}}}$

$\green{\tt{\therefore{Height\:of\:trapezium=15\:cm}}}$

$\orange{\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

$\green{\underline \bold{Given :}} \\ \tt: \implies Area \: of \:trapezium= 480\: {cm}^{2} \\ \\ \tt: \implies Parallel \: side \: of \: tapezium= 27 \: cm \: and \: 37 \: cm \\ \\ \red{\underline \bold{To \: Find :}} \\ \tt: \implies Height \: of \:trapezium = ?$

• According to given question :

$\bold{As \: we \: know \: that} \\ \tt: \implies Area \: of \: trapezium = \frac{1}{2}(Sum \: of \: parallel \: side) \times h \\ \\ \tt: \implies 480 = \frac{1}{2} \times (27 + 37) \times x \\ \\ \tt: \implies 480 = \frac{1}{2} \times 64 \times x \\ \\ \tt: \implies \frac{480}{32} = x \\ \\ \green{\tt: \implies x = 15 \: cm}$
