Question

The length of the rectangle is 10 centimetre and perimeter is 30 cm then what is the other side of the rectangle

Answer 1

l= 10 cm

b = ?

perimeter of rectangle = 2 x (l + b)

30 = 2 x ( 10 + b )

30 = 20 +2b

30 - 20 = 2b

10/ 2= b

b= 5

other side of the rectangle is 5cm

Answer 2

Answer:

5cm

Step-by-step explanation:

Perimeter of rectangle is 2*(length+breadth)

Perimeter=30cm (acc. to que)

Length of rectangle is 10cm

Putting these values in above formula, we get

30=2(10+b)

30=20+2b

30-20=2b

10=2b

Therefore, b=5

breadth = 5cm
