The length of the second base of a trapezoid is 17 ft.
What is the area of the trapezoid?
The area, A, of a trapezoid using the length of the midsegment is A = hm. Derivation. Substituting the value-form into the original trapezoid area formula:
The length of the second base of a trapezoid with one base measuring 12 ft, a height of 4 ft, and an area of 58 square ft.
The length of the second base of a trapezoid is;
[tex]\rm Area = \dfrac{1}{2} \times (Base_1+Base_2) \times height \\\\58 = \dfrac{1}{2} \times (12+Base_2) \times 4\\\\ 58 = (12+Base_2) \times 2\\\\\dfrac{58}{2}= (12+Base_2) \\\\ (12+Base_2)=29\\\\Base_2=29-12\\\\Base_2=17[/tex]
Hence, the length of the second base of a trapezoid is 17 ft.
