Given:
An isosceles trapezoid has a perimeter of 37 centimeters. Its shorter base measures 3 centimeters and its longer base measures 4 centimeters. The two remaining sides have the same length.
We need to determine the lengths.
Length of the remaining sides:
Let the length of the sides of the isosceles trapezoid be x.
Let a be the length of the shorter base.
Let b be the length of the longer base.
Thus, we have;
![a=3, b=4](https://img.qammunity.org/2021/formulas/mathematics/high-school/qtlnv150b74wtcb2huin6gu7axhn6nc3ko.png)
The formula to determine the length of the sides is given by
![Perimeter = a+b+c+d](https://img.qammunity.org/2021/formulas/mathematics/high-school/eo51ocwcq7wjpgy2j3kst96wjgj59emv4m.png)
Substituting the values, we get;
![37=3+4+x+x](https://img.qammunity.org/2021/formulas/mathematics/high-school/up40g33wynhgbobnl74m0i7d8xue51psea.png)
![37=7+2x](https://img.qammunity.org/2021/formulas/mathematics/high-school/b9uum44rtcc103jfhrsq8kyg3gxmnqilkg.png)
![30=2x](https://img.qammunity.org/2021/formulas/mathematics/high-school/xlwka4o3f0bayy26wx01g7chf4tb7766ro.png)
![15=x](https://img.qammunity.org/2021/formulas/mathematics/middle-school/hzusiqpxiqnvas0cnbynxvpd3widmdy735.png)
Thus, the length of the sides of the isosceles trapezoid is 15 centimeters.
