Question

solve qno 61fast please​

Answer 1

ANSWER:

OPTION (A) is correct that is 48

Step-by-step explanation:

□length of rectangle=16m

□breadth of rectangle=9m

AREA OF SQUARE = AREA OF RECTANGLE

${side}^{2} = l \times b \\ {a}^{2} = 16 \times 9 \\ {a}^{2} = 144 \\ a = \sqrt{144} \\ a = 12m \\ perimeter \: of \: square \: = 4 \times side \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 4 \times 12 = 48m$

Answer 2

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

${\bold{\therefore Perimeter\:of\:square=48\:m}}$

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

$\underline {\underline \bold{Given : }} \\ \implies \text{length = 16 m} \\ \\ \implies \text{breadth = 9 m } \\ \\ \implies \text{area \: of \: square = area \: of \: rectangle} \\ \\ \underline {\underline \bold{To \: Find: }} \\ \implies \text{perimeter \: of \: square =?}$

• According to given question :

$\bold{Finding \: area \: of \: rectangle : } \\ \implies area \: of \: rectangle = length \times breadth \\ \\ \implies area \: of \: rectangle = (16 \times 9)m \\ \\ \implies area \: of \: rectangle = 144 \: {m}^{2} \\ \\ \text{area \: of \: rectangle = area \: of \: square } \\ \implies area \: of \: square = 144 \\ \\ \implies side^{2} = 144 \\ \\ \implies side = \sqrt{144} \\ \\ \implies side = 12 \: cm \\ \\ \bold{Finding \: perimeter \: of \: square : } \\ \implies perimeter \: of \:square = 4 \times side\\ \\ \implies perimeter \: of \:square = 4 \times 12 \\ \\ \bold{\implies perimeter \: of \:square = 48 \: m}$
