Question

If a rectangles perimeter is 24cm and breadth is 5cm then what is the length

Answer 1

Answer:

7cm

Step-by-step explanation:

The perimeter of rectangle = 2( l + b)

Permit = 24cm

Permit = 24cm breadth = 5cm

24 = 2( l + b )

12 = 5 + l

12 - 5 = l

7 cm

7cm is the length of the rectangle

Answer 2

Perimeter of rectangle = 2 X ( length + breadth ) ……….. ( A )

Given that,

Breadth of rectangle = 4 cm

Perimeter of rectangle = 24 cm

Let length of rectangle = y cm

Putting values of Perimeter and Breath in Equation ( A ), We get

24 = 2X(y+4)

24 = 2y+8

24 − 8 = 2y+8−8

16 = 2y

16 / 2 = 2y / 2

8 = y

Therefore, the length of side of the rectangle is 8cm.
