Question

the perimeter of rectangular sheet is hundred centimetre if the length is 35 cm find its breadth and also find its area​

Answer 1

$\huge{\mathcal{\blue{\underline{Answer}}}}$

Breath of the rectangular sheet :

$2(l + b) = 100cm \\ 2(35cm + b) = 100cm \\ 35cm + b = \frac{100cm}{2} \\ 35cm + b = 50cm \\ b = 50cm - 35cm$

$\huge{\mathcal{\blue{\underline{breath=15cm}}}}$

Now the area of the sheet :

$= l \times b \\ = 35cm \times 15cm \\ = 525cm {}^{2}$

Answer 2

Answer:

perimeter of a rectangle =2(l+b)

100=2(35+b)

50=35+b

50-35=b

15cm=b

area of a rectangle = lb

area=35 * 15

area=525
