Answer 1

HOPE IT HELP U......

Answer 2

Answer:

5.25 m

Step-by-step explanation:

Let the length of rectangle be a, so, breadth = x/3

Perimeter of square = 40 m

Perimeter of Rectangle = (2/5 of 40) - 2

= 16 - 2 = 14 m

ATQ,

2(l+b) = 14

l + b = 7

x + x/3 = 7

3x + x = 21

4x = 21

x = 21/4

x= 5.25 m
