Question

The perimeter of a rectangle is 134cm if its lenght is 3 cm more than its breadth find the lenghth and breadth of the rectangle

Answer 1

Answer:

Let the breadth be x.

length=x+3

perimeter=134

therefore,

2(x+x+3)=134

4x+6=134

4x=134-6

4x=128

x=128/4=32

breadth=32 cm

length=32+3=35 cm

Answer 2

Given :

• Perimeter of a rectangle = 134 cm
• Length of rectangle is 3 cm more than breadth.

To find :

• Length and breadth of rectangle?

Solution :

☯ Let breadth of rectangle be x cm.

Then, Length of rectangle will be (x + 3) cm

Now,

★ According to the Question:

• Perimeter of a rectangle = 134 cm

As we know that,

✮ Perimeter of Rectangle = 2(length + breadth)

⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━⠀⠀⠀⠀⠀

Therefore,

➻ 2((x + 3) + x) = 134

➻ (x + 3) + x = 134/2

➻ 2x + 3 = 67

➻ 2x = 67 - 3

➻ 2x = 64

➻ x = 64/2

➻ x = 32

Hence,

• Breadth of rectangle, x = 32 cm
• Length of rectangle, (x + 3) = 32 + 3 = 35 cm

✮ More to know:

• Area of rectangle = length × breadth
• Diagonal of rectangle = √(length)² + (breadth)²
• Area of square = side × side
• Perimeter of square = 4 × side
• Diagonal of rectangle = √2 × side
