The relation between the length and breadth of the rectangle is given
length = breadth + 7
Also, the perimeter of the rectangle is 46 cm
Perimeter = 2 ( length + breadth )
46 = 2 ( breadth + 7 + breadth )
23 = 2(breadth) + 7
23 - 7 = 2(breadth)
16 = 2(breadth)
breadth = 8 cm
So, length = breadth + 7
= 8 + 7
= 15 cm
Area of the rectangle = length × breadth
= 8 × 15
= 120 cm²
Hence, the area of the rectangle will be 120 cm²
So, option 1) will be the correct answer
