Question

The perimeter of a rectangular sheet is 120 cm. If the length is 30 cm, find its breadth​

Answer 1

Answer:

Breadth of the rectangular sheet is 30 cm.

Step-by-step explanation:

Given:

Perimeter of a rectangular sheet = 120 cm.

Length of the rectangular sheet = 30 cm.

We know that ,

Perimeter of rectangle = 2 ( length + breadth)

                            120 = 2 ( 30 + breadth)

                         120 / 2 = 30 + breadth

                         60 - 30 = breadth

                             30= breadth

Answer 2

Answer:

GIVEN

PERIMETER (p)=120cm

LENGTH(l)=30CM

BREATH(b)=?

FORMULA OF PERIMETER OF RECTANGULAR

$p = 2 \times l + b$

SO ACCORDING TO QUESTION

P=2(l+b). ____PUTTING VALUE of Length and perimeter

120=2(30+b)

120=60+2b

2b=120-60

b=60/2

b=30cm
