Answer 1

Answer:

Step-by-step explanation:

Answer:

Perimeter of rectangle = 60 cm

Width of the rectangle (b) = 10 cm

Length of the rectangle (l) = ?

Perimeter of rectangle = 2 ( length + breadth )

60 = 2 ( length + 10 )

60 / 2 = length + 10

30 = length + 10

length = 30 - 10

Length = 20 cm

Proof :-

Perimeter of rectangle = 2 ( length × breadth )

2 ( 20 + 10 )

2 × 30

60 cm

:. Perimeter of rectangle = 60 cm

Hence You Got Your Answer .
