Question

A rectangle garden with 20m as its perimeter and breadth as 4m what is it's length

Answer 1

Answer:

Step-by-step explanation:

Perimeter of a rectangle = 2 ( l + b )

2(l + b) = 20 m

2 (l + 4) = 20 m

2l + 8    = 20

2l           = 20 - 8

             = 12

l             = 12/2 = 6

Therefore ,

Length of the rectangle is equal to 6 m

Answer 2

Perimeter of garden -20 m

Breadth of garden - 4m

Length of garden -??

Perimeter of rectangular garden- 2*(L+b)

20 m =2* (L+4) m

20/2 m = L+4 m

10 m =L +4 m

10 m -4 m= L

L = 6 m

Answer is 6 m
