Hope this answer is helful. All the best. ☺☺

Answer 2

Answer:

4 m

Step-by-step explanation:

The base is nothing but the breadth (say b) and the height is the length (say l) of the rectangle.

Thus,

2 ( l + b ) = 40

l + b = 20 ----- ( 1 )

Given : b = 5l - 4

Thus, in ( 1 ),

l + ( 5l - 4 ) = 20

6l = 24

l = 4

Thus, ANS = 4 m
