Question

6. The breadth of a rectangle is 12 m. If its length is 3
times its breadth, find the perimeter of the rectangle.​

Answer 1

Answer:

30

Step-by-step explanation:

12×2+3×2 we multiplied both by two because rectangles have 4 sides= 2 length and 2 breadth

Answer 2

Answer:

Breadth = 12m

Let the length of rectangle be 3b.

So,length = 3×12 = 36 m

Perimeter of rectangle = 2×(l+b)

= 2×(36+12)

=2×(48)

= 96 m
