Answer:
Breadth = 10 cm
Length = 15 cm
Step-by-step explanation:
Let the breadth = x cm
Length = (x + 5) cm
Perimeter of a rectangle = 50 cm
2 *( length + breadth) = 50
2*(x + 5 + x) = 50
Combine like terms
2*(2x + 5) = 50
2*2x + 2*5 = 50
4x + 10 = 50
Subtract 10 from both sides
4x = 50 - 10
4x = 40
Divide both sides by 4
x = 40/4
x = 10
Breadth = x = 10 cm
Length = x +5 = 10 + 5 = 15 cm
