Answer 2

Answer:

152cm

Step-by-step explanation:

So you know the breadth is 19cm.

And you also know the length is 3 times more than the breadth.

So to find the length you must do (19 x3) which is 57cm

To find the perimeter of a shape you add up all the lengths and breadths of the shape.

A rectangle has two lengths and two breadths.

so you do 19cm+57cm+19cm+57cm

that is 152cm
