Question

Perimeter of a rectangle is 2m less than 2/5 of the perimeter of a square. If the perimeter of the square is 40m, find the length and breadth of the rectangle given that the breadth is 1/3 of the length.​

Answer 1

Answer:

Step-by-step explanation:

Perimeter of square = 40cm

Perimeter of rectangle = 40*(2/5) - 2 = 16-2 = 14

Let length of rectangle be x

So breadth = x/3

So 2(x+x/3) = 14

x+x/3= 7

3x+x = 21

4x = 21

x = 21/4

Length = 21/4

Breadth = x/3 = 21/12 = 7/4
