Question

a rectangular picture is 60 m wide and 1.8m long . find the ratio of perimeter to area

Answer 1

perimeter= 2× (l+b)
=2×(60+1.8)m
=2×(61.8)m
=123.6m
area = l×b
= 60×1.8 m2
=108m2
ratio of perimeter to area=
[tex] \frac{123.6}{108 } \\
ratio= 3.09:27

Answer 2

hey friend

always

length > wide

so

l = 60m

b = 1.8m

so the perimeter = 2(60 + 1. 8

= 2(61.8)

= 123.6m

and the of rectangal = 60 (1.8)

= 108 m^2

so the ratio

perimeter : area

= 123.6 : 108

= 103 : 90
