Question

Q2) The length of a rectangular field is twice its breadth. If the perimeter of the field is 45 meters, find the length and breadth of the field? (03)​

Answer 1

Answer:

Let breadth be x m

then length is 2x m

Perimeter = 45 m

2 ( 2x + x) = 45

•°• x = 45 /6 = 15/2 = 7.5m

So, length= 15m

and breadth = 7.5m

Step-by-step explanation:

Answer 2

GIVEN :--

Let the breadth be x metres,

Then,

The length will be 2x.

Now,

we know,

That,

Perimeter = 2 × ( length + breadth )

45 = 2 × ( x + 2x )

45 = 2x + 4x

45 = 6x

x = 46 ÷ 6 x = 7.5

Therefore,

Length = 2x = 7.5 × 2 = 15 (ans)

Breadth = x = 7.5 (ans)
