Answer the following question:


The perimeter of rectangular sheet is 100 cm if the length is 35 cm , find its breadth also find its area.​

Answer 1

Answer:

Perimeter = 2 x (length + breadth)

100 = 2 x (35 + breadth)

50 = (35 + breadth)

Breadth = 15 cm

Area = length x breadth

Area = 35 x 15

Area = 525 cm²

Answer 2

Answer:

15

Step-by-step explanation:

Formula for perimeter of rectangle is Perimeter = 2 × (Length + Breadth)

⇒ Put the values in the values in the formula

⇒ Perimeter = 100

⇒ Length = 35

⇒ 100 = 2 × (35 + Breadth)

⇒ 100/2 = 35 + Breadth

⇒ 50 = 35 + Breadth

⇒ 50 - 35 = Breadth

⇒ 15 = Breadth

⇒ 15 is the Perimeter.

Area = length x breadth

Area = 35 x 15

Area = 525 cm²
