A.
The perimeter of rectangle EFGH is 7 times greater than the perimeter of rectangle ABCD.
B.The perimeter of rectangle ABCD is 7 times greater than the perimeter of rectangle EFGH.
C.The perimeters of the rectangles are equal
D.The perimeter of rectangle EFGH is 49 times greater than the perimeter of rectangle ABCD
WHAT IS THE ANWSER

B. Each side is 7 times as big, so the perimeter is also 7 times as big.

you rectangle thee EFGH 7 times ang you rectangle the ABCD perimiter the ABCD
