Question

The length of a wall 5 less than two times its breath. What is the perimeter of the wall. If its breath is 10 m?​

Answer 1

Answer:

150m

Step-by-step explanation:

perimeter of rectangle is length×breadth

length=2(10)-5 breadth=10m

so, perimeter=length×breadth

= [2(10)-5]×10

= (20-5)×10

= 15×10

=150m answer

Hope this answer will help you

Answer 2

Answer:

given that,

length=5 less than two times it's breath

perimeter=10

Step-by-step explanation:

length=(2×10)-5

= 15meter

perimeter =2(l+b)

=2(15+10)m

=2×25=50 m

hence, 50m is the perimeter of the wall
