Question

lenght of a rectangle is 3m less than four time is breadth .if the perimeter of the rectangle is 94m find it lenght and breadth​

Answer 1

Hey! check the attachment above....

Perimeter of rectangle = 2(lenght + breadth)

Answer 2

Given :

• Length of rectangle is 3 m less than four times breadth.
• Perimeter of Rectangle = 94 m

To find :

• Length and breadth of rectangle?

⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━━━⠀

☯ Let breadth of rectangle be x m.

Then, Length of rectangle is (4x - 3) m

Now,

★ According to the Question:

• Perimeter of Rectangle is 94 m.

As we know that,

Perimeter of rectangle = 2(length + breadth)

Therefore,

➯ 2[(4x - 3) + x] = 94

➯ (4x - 3) + x = 94/2

➯ 5x - 3 = 47

➯ 5x = 47 + 3

➯ 5x = 50

➯ x = 50/5

➯ x = 10

Hence,

• Breadth of rectangle, x = 10 m
• Length of rectangle, (4x - 3) = 40 - 3 = 37 m

★ More to know :

• Area of rectangle = length × breadth
• Diagonal of rectangle = √(length² + breadth²)
• Area of square = side × side
• Perimeter of square = 4 × side
• Diagonal of square = √2 × side
