1. Given : ABCD is a rectangle whose area is 108 m² and length is 12m
   

   To Find : area of the square AEFC

   Solution:

   Area of rectangle = length * breadth

   area = 108 m²

   length = 12 m

   => 12 * breadth = 108

   => breadth = 9 m

   diagonal of rectangle AC = √length² + breadth²

   = √12² + 9²

   = √225

   Area of square AEFC = AC² = (√225)² = 225 m²

2. Step-by-step explanation:

   given area= 108m²

   given length= 12m

   area= length × breadth

   108= 12x b

   b= 9 m

   we need to find the diagonal AC because AC is the side of the square. all sides of the square are equal.

   9²+12²= AC²

   81 + 144= AC²

   AC= 15 m

   area of square =15²

   area= 225 m²
