Question

The perimeter of a rectangle is 230 cm. if the length of the rectangle is 70cn, find it's breadth and area.​

Answer 1

Step-by-step explanation:

For a Rectangle ,

Perimeter = 2 × ( length+breadth)

230 = 2 × ( 70 + breadth )

115 = 70 + breadth

breadth = 115-70 = 45 cm

Area of Rectangle = length × breadth

= 70 × 45 = 3150 cm²

Answer 2

Hey..! Here is your answer ,

• Perimeter of a rectangle = 230 cm
• length of a rectangle = 70 cm
• Breadth = ?????

• Perimeter = 2 ( l + b )

• 230 = 140 + 2b
• 2b = 230 - 140
• 2b = 90
• b = 90

2

• Breadth = 45

• Area of a rectangle = Length × Breadth

= 70 × 45

= 3150 cm²

Hope it helps uh..!!
