Question

the perimeter of rectangle is 46 CM if its width is 3 cm more than one third of the length find the Length and width of rectangle

Answer 1

perimeter = 2l +2b
=2(l+b)=46
l+b=46/2=23

given statement.
width = 3+1/3length

=l+3+1/3l=23
l+1/3l =20
4/3l =20
l=20×3/4=15cm

l+b=23
15+b=23
b=23-15=8cm
