Value Based Question
As part of 'Earth Day' celebrations a
was arranged between nine section
Day celebrations an interclass poster making compe
tween nine sections of Class-VIII. Each section was provide
caring 75 cm x 40 cm for making the poster.
Find the total area of sheet provided to the students. Express the area
exponential form.
(b) Write any two ways by which you can save earth.
find the total area of sheet provided to the students express the area of exponential form
​

Answer 1

Step-by-step explanation:

area of sheet = 75 × 40 cm ^2 =3000 cm^2

in 1 section = 3000 cm ^2

in 9 section = 3000 × 9 cm ^2

27000 =(30)^2

Answer 2

Answer:

$\huge\rm{Solution} \:$

$\rm{value \: based \: questions }$

$\huge\rm\pink{a) }$

$\rm{ total \: number \: of \: sheets = 9 }$

$\rm{ area \: of \: sheet \: provided \: for \: 1 \: section} \\ \rm{ = 75 \times 40}$

$\rm{ area \: of \: sheet \: provided \: for \: 9 \: sections} \\ \rm\underline{ 75 \times 40}\rm{ \times 9}$

$\rm{ = 3000 \times 9}$

$\rm{ = 27000 \: c {m}^{2} }$

$\rm{ = 30 \times 30 \times 30}$

$\rm{ = (30 {)}^{2} \: c {m}^{2} }$

$\rm{(exponential \: form \: ) }$

$\huge\rm\red{b)}$

$\rm{two \: ways \: by \: which \: we \: can \: save \: } \\ \rm{earth \: are \: - }$

$\rm{ i) \: planting \: more \: trees}$

$\rm{ii) \: by \: keep \: environment \: clean }$
