Question

the ratio between the area and the perimeter of rectangular sheet of paper is 7:5. If the area of a sheet is 35cm² , find its perimeter​

Answer 1

Answer:

perimeter of rectangular sheet=25cm

Step-by-step explanation:

area of rectangular sheet=35cm^2

perimeter of rectangular sheet= x

35/x=7/5

35×5/7=x

25=x

hence,perimeter of rectangular sheet=25cm

Hope it's help you!!

Answer 2

Answer:

Let the sides be = 7x,5x

${\fcolorbox{cyan}{lime}{Area=length×breadth}}$

${35}^{2} = 7x \times 5x \\ \\ = 35= 35x \\ \\ = x = \frac{35}{35} \\ \\ = x = 1$

So, length =7x= 7cm

Breadth= 5x= 5cm

Perimeter = 2(length+breadth)

= 2(7+5)

= 2×12

= 24cm
