Correct Answer - Option 1 : 15 cm
Given:
Length of rectangle = 8 cm
Breadth of rectangle =7 cm
Formula:
Perimeter of square = 4 × a
Perimeter of rectangle = 2 × (L + B)
Calculations:
Perimeter of a square = 2 × perimeter of a rectangle
Perimeter of a square = 4 × side
Perimeter of a rectangle = 2(length + breadth)
Given Rectangle of length = 8 cm and breadth = 7 cm
Perimeter of a rectangle = 2(8 + 7) = 2 × 15 = 30 cm
So, Perimeter of a square = 4 × side = 2 × perimeter of a rectangle
⇒ 4 × side = 2 × 30
⇒ Side = 15 cm
∴ Side of the square is 15 cm
