find the ratio of perimeter to area of rectangle having length & breadth are of 3and 2 cm . respectively​

Answer»

Given :-

  • Length of the rectangle = 3cm
  • Breadth of the rectangle = 2cm

To find :-

  • The ratio of the rectangle's perimeter to area

In order to find the ratio, let us calculate the area and perimeter respectively.

Area of the rectangle :-

→ Length × Breadth

SUBSTITUTING the values,

→ 3cm × 2cm

→ 6cm²

Perimeter of the rectangle :-

→ 2(Length + Breadth)

Substituting,

→ 2(3 + 2)

→ 2(5)

→ 10cm

Ratio :-

Ratio is the relation between any two or more quantities or COMPARISON between any two or more quantities expressed in the simplest FORM.

Ratio of the perimeter to the area is :-

10 : 6

Expressing it in the simplest form,

[Here both of the numbers are MULTIPLES of 2, hence by DIVIDING both by 2 we get the required ratio]

→ 5 : 3

Therefore,

The ratio of a rectangle's perimeter to area is 5:3
