Question

The measure measure of two adjacent side of a rectangle in is in the ratio 7 ratio 3 if the perimeter of rectangle is 84 CM then find its length and breadth

Answer 1

Let the ratios be in x then,

2(l+b)=perimeter

2(7x+3x)=84

2(10x)=84

20x=84

X=84/20

X=4.2

Length =7x=7x4.2=29.4cm

Breadth =3x=3x4.2=12.6
