[tex]\rm{\huge{ANSWER:}}[/tex]

[tex]\bold{\red{GIVEN}}[/tex]

  • Area of the trapezoid = 780 cm²
  • Height of the trapezoid = 30 cm
  • One base of the trapezoid = 20 cm

[tex]\bold{\red{FORMULA}}[/tex]

  • Area = ([tex]\large{\frac{1}{2}}[/tex]) x (sum of the bases) x height

[tex]\bold{\red{SUBSTITUTE}}[/tex]

  • 780 = ([tex]\large{\frac{1}{2}}[/tex]) x (20 + b) x 30

[tex]\bold{\red{SOLVE~FOR~B}}[/tex]

  • 780 = 300 + 15b
  • 480 = 15b
  • b = 32cm

[tex]\bold{\red{CONCLUSION}}[/tex]

  • The length of the other base of the trapezoid is [tex]\underline{\large\sf\red{32 ~cm}}[/tex].
