D) 3 cm

Explanation:

area = 1/2(b1 + b)(h)

91 = 1/2(10 + b)(14)

simplify:

91 = (5 + 1/2b)14 = 70 + 7b

subtract 70 from each side of the equation:

21 = 7b

b = 3

Explanation:

Area of trapezoid=91cm²

height[h]=14cm

one base[B]=10cm

another base[b]=b(let)

we have

Area of trapezoid=91cm²

½×h[B+b]=91cm²

½×14[10+b]=91

10+b=91/7

b=13-10

b=3

So another base's length is 3cm.
