Question

The perimeter of the rectangle is given as twice the sum of its
length and breadth. The breadth of a rectangle is thrice its length,
'y'. Express the perimeter in terms of 'y'.​

Answer 1

Answer:

2×(3y+y)

Step-by-step explanation:

As we know The perimeter of the rectangle is given as twice the sum of its length and breadth.

Length= y

Breadth=thrice length of y=3y

So 2(l+b)

=2(y+3y)

Answer 2

Answer:

we know

perimeter of rectangle

=2×(L+B)

As from question

breadth of rectangle =3×length of rectangle

Now, Perimeter of rectangle = 2×(length+3×length)

=". " (p) = 2×(y+3×y)

= p= 2×(4y)=. Perimeter = 8y

SO PERIMETER OF RECTANGLE =8y Ans
