I believe it is C but then again I'm not sure good luck though
Answer:
Area of the square is 2916
.
Step-by-step explanation:
Let the breadth of the rectangle be represented by w. So that;
length of rectangle = 5w
Area of rectangle = length x breadth
= 5w x w
1620 = 5
divide through by 5 to have,
= 324
w = 
= 18
Thus, the breadth of the rectangle is 18 m.
length = 5 w = 5 x 18
= 90 m
The length of the rectangle is 90 m.
Perimeter of the rectangle = 2(l + w)
= 2( 90 + 18)
= 216 m
Perimeter of a square = 4l
where l is the length of its side.
Given that the perimeters of the rectangle and square are equal, then;
4l = 216
l = 
= 54
length of the side of square is 54 m.
Therefore,
Area of square = 
= 
= 2916
Area of the square whose perimeter is equal to that of the rectangle is 2916
.
The correct answer here is that the sum has to be 84. This is due to the
fact that 30 + 54 is 84, and the greatest common factor is 6 because
the factors of 30 are 1, 2, 3, 5, 6 , 10, 15, and 54's Factors: 1, 2, 3,
6, 9, 18, 27, and 54, so from this we can see that 6 is the great
common factor.
