Question

the breadth and the perimeter of a rectangle field are 30cm and 1.8 meters respectively find the lenght of the field​

Answer 1

Answer :

• Length of rectangular field = 60 cm.

Given :

• The breadth and the perimeter of a rectangular field are 30 cm and 1.8 meters respectively.

To Find :

• The length of the field.

Step By Step Explanation :

As given in the question the breadth and the perimeter of a rectangular field are 30 cm and 1.8 meters or 180 cm respectively.

We need to find the length.

So let's do it !!

Let us consider length be x.

We know that ⤵

$\dag\boxed{\bf{\purple{Perimeter_{(Rectangle)} = 2(Length + Breadth)}}}$

By substituting the values ⤵

$\longmapsto \sf180 = 2(x + 30) \\ \\ \longmapsto \sf180 = 2x + 60 \\ \\ \longmapsto \sf180 - 60 = 2x \\ \\ \longmapsto \sf120 = 2x \\ \\ \longmapsto \sf \cancel\cfrac{120}{2} = x \\ \\\longmapsto {\bf{ \red{60 \: cm= x}}}$

Therefore length of rectangular field = 60 cm.
