Step-by-step explanation:
1. solution,
length of rectangle A(l)=3.1units
breadth of rectangle A(b)=1units
now,
area of rectangle A=l×b
=3.1units×1units
=3.1 sq units
2.solution,
length of rectangle B(l)=3.1units
breadth of rectangle B (b)=0.4units
now,
area of rectangleB=l×b
=3.1units×0.4units
=1.24 sq units
3.solution,
length=3.1units
breadth=1.4units
area =lxb
=3.1units x 1.4units
=4.34units
Answer:

Step-by-step explanation:






Equations:
100 + 35m
50 + 35m
Steps:
100 + 35m = 50 + 35m <span>
<em>Set the equations equal to each other.</em>
</span> <span />
<span>
100 + 35m = 50 + 35m <span>
-50 - 50
</span>
<em>Subtract 50 from both sides of equation to isolate the variable on one side</em>.
50+35m=35m
-35m -35m
<em>Subtract 35m from both sides of equation.</em>
50=m
In fifty months, they will have the same amount of money. They will each contain $1850 dollars.
