Question

if length is 5cm and perimeter is 24cm then what is the breadth​

Answer 1

Answer:

Perimeter of rectangle = 24cm

Length = 5cm

Let the breadth be x.

Perimeter = 2 ( length + breadth)

24 = 2 ( 5 + x)

24 = 10 + 2x

24 - 10 = 2x

14 = 2x

14/2 = x

7 = x

So, the breadth of rectangle is 7 cm.

Answer 2

Answer:

perimeter = 2( l + b )

24cm = 2 ( 5cm + b )

24cm = 10cm + 2b

24cm - 10cm / 2 = b

14cm / 2 = b

7cm = b

breadth = 7cm
