Question

The perimeter of a rectangular sheet is 100 cm. If the length is 35 cm, find its breadth. Also find the area.​

Answer 1

Answer:

15 cm

Step-by-step explanation:

Very easy question dude

As you know that perimeter of rectangle = 2(l + b)

So, given Length = 35cm

So,

2(35cm + b) = 100cm

70cm + 2b = 100cm

2b = 100cm - 70cm

2b = 30cm

b = 30cm/2

b = 15 cm

Mark me as brainiest your point will return

Answer 2

Answer:

15cm, 375cm²

Step-by-step explanation:

Perimeter=100cm

Length = 35cm

Breadth = b

perimeter of rectangle = 2(l+b)

100cm = 2 (35+b)

100cm = 70 + 2b (after opening the bracket)

2b = 100cm - 70cm

2b = 30

b = 30/2

b = 15 cm

Area of rectangle = lxb

                             = 35 x 15

                             = 375 cm²
