Question

a picture is 60cm wide and 1.8cm long.The ratio of its perimeter to its width in the lowest form is
​

Answer 1

Answer:

Answer: The required ratio is 1:8

Step-by-step explanation:

Width\breadth of picture = 60 cm

Length of picture = 1.8 m = 180 cm

Let P is the perimeter , l is length and b is breadth then

P= 2(l+b) = 2( 60+180) = 480P=2(l+b)=2(60+180)=480

Now ratio of width to its perimeter is given by

\dfrac{width}{perimeter} =\dfrac{60}{480} =\dfrac{1}{8}

perimeter

width

=

480

60

=

8

1

Hence, the required ratio is 1:8

Answer 2

Step-by-step explanation:

Length=1.8cm

Breadth=60cm

Perimeter=2×(l+b)

=2×(1.8+60)

=2×61.8

=123.6cm

Ratio=123.6:60

=123.6/60

=1236/600

=103/50 (In simplest form)

=103:50
