Question

half the perimeter of rectangular park is 31m.Its length is 3 more than its width . The dimensions of the park is(.correct answer will be marked as brain list) ​

Answer 1

Step-by-step explanation:

perimeter =2 (1+b)

half peri. 31m= (l+b)

let breadth=x

length= 3x

perimeter 2×31 = 62m

perimeter = 2 (l+b)

62= 2 (3+x+x)

31= 3+2x

31-3-2x

28= 2x

28/2=X

14=x

breadth=14

length= x+3

=14+3

=17
