Question

The length of rectangle garden in 8 more than its breadth.find the length and breadth of the garden if it's perimeter is 280 ​

Answer 1

Answer:

Let the breadth be x.

Step-by-step explanation:

Length =8 +x

Breadth = x

perimeter = 280

A/q , We know that = perimeter of rectangle = 2(l+b)

280 = 2 (8x+x)

280 = 2× 9x

280 = 18x

x = 280÷18

× = 15.56 Answer.

Answer 2

Given :

• Perimeter of the rectangular garden = 280 m.
• The length of rectangle garden in 8 more than its breadth.

To find :

• Dimensions of the rectangle =?

Formula Used :

• Perimeter of the rectangle = 2(length + breadth)

Step-by-step explanation :

It is Given that,

Perimeter of the rectangular field = 280 m.

The length of rectangle garden in 8 more than its breadth.

Now,

Let, the breadth of the rectangle be, x.

Then, the length of the rectangle be, x + 8.

As We know that,

Perimeter of the rectangle = 2(length + breadth)

Substituting the values in the above formula, we get,

280 = 2 (x + x + 8)

280 = 2(2x + 8)

280 = 4x - 16

4x = 280 - 16

4x = 264

x = 264/4

x = 66.

Hence,

The breadth of the rectangle, x = 66 m

Then, the length of the rectangle, x + 8 = 66 + 8 = 74 m
