Question

A rectangle is having length 30 cm and breadth 25 cm.  A square region of side 5 cm is cut out from it. Find the area of the remaining portion.


  1. 750 cm2

  2. 625 cm2

  3. 725 cm2

  4. 700 cm2


Solution

The correct option is C

725 cm2


Area of rectangle = length x breadth

Area of rectangular region = 30 x 25 
= 750 cm2

Given, side of square cut out = 5 cm

Area of square = 5 x 5
= 25 cm2

Area of the remaining portion = area of rectangle - area of square.
=750 - 25
= 725 cm2
