• The breadth is 8 cm

To find :

The length of the rectangle

Formula Used :

Area of a rectangle = Length × Breadth

Step 1 of 2 :

Form the equation to calculate length of the rectangle

Area of the rectangle = 80 sq.cm

Breadth of the rectangle = 8 cm

Let length of the rectangle = L cm

Area of a rectangle = Length × Breadth

So by the given condition L × 8 = 80

Step 2 of 2 :

Calculate length of the rectangle
