The width of a rectangle is 2/3 of it`s length if the perimeter of the rectangle is 80 cm. Find length and width.

${\huge{\bf{\purple{\mathbb{\underline {Answer:-}}}}}}$

24 and 16cm

${\huge{\bf{\purple{\mathbb{\underline {Explanation}}}}}}$

let the length be a

so, width =2a/3

According to question,

perimeter = 2(L+B)

80=2(L+B)

40=L+B

40=a+2a/3

40×3= 5a

a=24

so the length is 24 cm and width is 16 cm Answer.
