Answer :
Breadth = 41/4 cm is the answer...
Explanation :
Perimeter of the rectangle = 26 cm
Length = 2 3/4 cm = 11/4 cm
Let the Breadth be in 'x'
Perimeter = 2 × ( Length + Breadth )
=> 26 = 2 × ( 11/ 4 + x )
=> 26 = 11/2 + 2x
=> 26 - 11/2 = 2x
=> 41/2 = 2x
=> 41/2 ÷ 2 = x
=> 41/2 × 1/2 = x
=> 41/4 = x
x = 41/4
