The length and breadth of a rectangular playground are 110m and 90m. Find the ratio of:

(a) length to perimeter

(b) perimeter to breadth

The length and breadth of a rectangular playground are 110m and 90m.

(a) Ratio of length to perimeter = 11 : 40

(b) Ratio of breath to perimeter = 9 : 40

Solution:

Given that length of play ground = 110 m

And breadth of playground = 90 m

Need to determine ration of (a) length to perimeter and (b) perimeter to breadth

Lets first calculate perimeter of rectangular playground

Perimeter of Rectangle = 2 (length + breadth)

=> Perimeter of Rectangular playground = 2 (110 + 90) = 400 square meter

Now substituting values in ratio we get,

(a) Ratio of length to perimeter = 110 : 400 = 11 : 40

(b) Ratio of breath to perimeter = 90 : 400 = 9 : 40
