Question

5. The perimeter of a rectangular field is km. If the length of the field is twice its width, find its area in square metres.​

Answer 1

Step-by-step explanation:

I am telling u the formula because u have not given the perimeter if that rectangular field.

We know that,

Perimeter of a rectangle = 2×(l+b)

So, Let the width be x.

Then, the length will be 2x.

Now take the equation and solve for x:-

Perimeter=2×(2x+x)

(Given)

After knowing the value of x, Find its length and width.

After that,

We know the formula of area=

Length × Width

So, by this process u can find ur answer i had not done the answer and written only formulas because in question the perimeter is not given......

Hope it helps u...!!
