Question

2. The perimeter of rectangle is 20 cm. If the length of rectangle is 6 cm, then its breadth will be: *

Answer 1

Answer:

Step-by-step explanation:

Perimeter of Rectangle = 2(l+b) = 20 cm

Length (l) = 6cm

Breadth = x cm

Perimeter = 2 ( 6 + x ) = 12 + 2x = 20cm

Perimeter = 2x = 20-12

Perimeter = x = 8/2

Breadth = 4cm

Answer 2

Solution :

Given

Perimeter of an rectangle = 20 cm

length = 6 cm

using the formula of perimeter of rectangle = 2( length + breadth )

Perimeter = 2\left [ l+b \right ]

20 = 12 +2b

20-12 = 2b

8 = 2b

b= 4cm

breadth of the rectangle = 4cm
