1 meter = 10 decimeters (multiply both sides by 10)
5 meters = 50 decimeters (multiply both sides by 5)

10. Equation: $9.25 - $4.50 - 3.50 = m
Answer: $1.25
Step by step:
Perimeter = Summation of all sides = AB+BC+CD+DA = 2x+2+x+2x+2+x=(6x+4)
⇒6x+4=154
⇒6x=154−4
⇒
⇒25=x
The breadth is x=25
The length of the rectangular pool = (2×25+2)=50+2=52m
<em>breadth </em>is 25 and the<em> length </em>is 52
