You need to know the other base as it may be different.
Answer is one half the sum of bases times height ) 1/2 (b1 + b2)(h)
The formula to calculate the area of a trapezoid is (1/2) * sum of the bases * height. Given that the height is 12 cm and the bases are 15 cm and another side, the area can be calculated as (1/2) * (15 + b) * 12, where b is the length of the other base.

For a parallelogram, take the base times the height. For a trapezoid, take the smaller base and times it by the height.
Area of a triangle = 1/2 (Base x Height) Example: Width 13cm, Height 5cm, Base 12cm then; Area=1/2(12cm x 5cm) Area=6cm x 5cm Area=30cm2
Area of a trapezoid = 0.5*(sum of parallel bases)*height Need to know the measure of the other base
The perimeter of a trapezoid is the sum of its bases and legs. The area of a trapezoid is the height times (base 1 + base 2) divided by 2
this is 5cm (:

The area is 108cm2
Area is 36cm2
For a parallelogram, take the base times the height. For a trapezoid, take the smaller base and times it by the height.

The height of the trapezoid is also needed to find its area which is as follows:- Area of a trapezoid = 0.5*(sum of bases or parallel sides)*height
Height of trapezoid = 2*area/sum of parallel sides
Area of a trapezoid = 0.5*(sum of parallel bases)*height Need to know the measure of the other base
The perimeter of a trapezoid is the sum of its bases and legs. The area of a trapezoid is the height times (base 1 + base 2) divided by 2
The area of a trapezoid is: base 1 + base 2 times height divided by 2. :) I hope I helped you out a bit ^^
base times height then that divided by 2
