Question

The length of this rectangular park is 20 m.
The area of the park is A square metres.

Which calculation gives the perimeter (P) of the park in metres?

Answer 1

Answer:

let breadth be b

area=l×b=A=20

b=20/A

perimeter=2(l+b)=2(20+20/A)

Answer 2

Solution :-

Let us assume that, the breadth of the rectangle is b m .

So,

→ Length * Breadth = Area of park

→ 20 * b = A

→ b = (A/20) m

then,

→ Perimeter of park = 2(Length + Breadth)

→ Perimeter of park = 2{20 + (A/20)}

→ Perimeter of park = 2{(20*20 + A)/20}

→ Perimeter of park = {(400 + A)/10} m or , {40 + (A/10)} m .

Now, please match perimeter of park with given options .
