Question

1. The length of a rectangle with perimeter 24 cm and breadth of 4 cm is​

Answer 1

Step-by-step explanation:

perimeter of rectangle =2× (Length+breadth)----(1)

Given that ,

Breadth of rectangle = 4 cm.

Perimeter  of rectangle =24 cm.

Let length of rectangle = y cm.

putting the values of perimeter and Breadth in (1)

24=×(y+4)

⇒24=2y+8

⇒2y=24−8

⇒2y=16

⇒y=16/2

⇒y=8.

Therefore, the length of side rectangle is 8 cm.

Answer 2

L = ?

B = 4 cm

P = 24 cm

Step-by-step explanation:

Perimeter of rectangle = 2 (L+B)

Put the values,

24 = 2 (L+4)

24 = 2L + 8

2L + 8 = 24

2L = 24 - 8

2L = 16

L = 16/2

L = 8

Hence, the length of the rectangle is 8 cm.
