Question

Find the perimeter of a rectangle whose length is 3x meters and breadth is 2x meters ​

Answer 1

length = 3x

breadth = 2x

According to the sum:

2(3x + 2x) = perimeter

2 × 5x = perimeter

10x = perimeter

x = perimeter / 10

Answer 2

Answer:

length = 3x

Breadth = 2x

According to the sum :2(length+breadth)

2(3x + 2x) = perimeter

2 × 5x = Perimeter

10x = Perimeter
