The area of rectangle is 120 metre square and its breadth is 8 metre. Find the length of the rectangle and perimeter of the rectangle.

Given: 

Area of the rectangle = 120 m

Breadth of the rectangle = 8 m

To find: Here we have to find the length of the rectangle and perimeter of the rectangle.

Solution:

We know that:

Area of rectangle = Length $\times$ Breadth

Also, given that;

Area of the rectangle = 120 m² 

So,

Length $\times$ Breadth = 120 m² 

Length $\times$ 8 m = 120 m² 

Length $\times$ 8 m = 120 m² 

Length = $\frac{120}{8}$ m

Length = 15 m

Now,

Perimeter = 2(Length $+$ Breadth)

Perimeter = 2(15 $+$ 8)

Perimeter = 2(23)

Perimeter = 46 m

So, length of the rectangle is 15 m and Perimeter is 46 m.
