Answer:
54 square meters
Step-by-step explanation:
Similar figures have corresponding lengths as equal ratios.
Smaller trapezoid's base is given 12 and larger trapezoids base is given 18, so the scale factor is 
<em>this means the lengths of larger is 1.5 times lengths of smaller.</em>
<em />
In terms of area, the scale factor is squared. Hence the scale factor for area is 
<em>this means the area of larger is 2.25 times the area of smaller.</em>
<em />
Now, Let area of smaller trapezoid be x so we can say: 
<em>to nearest square meter, </em><em>x = 54 meters squared</em>
Develop two linear equations to represent the savings of these two people:
Raul: rl=$350 + $15x
Ruth: rh=$200 + $25x
In both cases, x represents the number of weeks elapsed.
When will these two people have saved up the same amount? Set rl = rh and solve for x, the number of weeks elapsed:
$350 + $15x = $200 + $25x
$150 = $10x gives us x= 15. Their savings will be equal after 15 weeks.
The total surface area would be 370.58 square units.
