Question

If ABCD is a rectangle whose area is 108m2 and length is 12m , then the

area of the square AEFC is ​

Answer 1

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

Answer 2

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
