Question

The perimeter of a rectangle is 25cm and breathe is 5 3upon4cm .find its length

Answer 1

• Breath =23 / 4 cm

We know
Perimeter of rectangle = 2 (l +b )
25 = 2 ( l +23 /4 )
25/2 = ( 4l + 23 / 4 )
25 ×4 / 2 = ( 4l + 23 )
50 = 4l + 23
50 - 23 = 4l
27 = 4l
l = 27 / 4

Therfore L = 27/ 4 cm !!
