we know that
The area of a trapezoid is given by the formula
Area=h*(b1+b2)/2
where
b1, b2 are the lengths of each base
h is the altitude (height)
Remember that the bases are the two parallel sides of the trapezoid. The altitude (or height) of a trapezoid is the perpendicular distance between the two bases
therefore
[area of trapezoid]=(11+5)*4/2--------> 64/2------> 32 cm²
the answer is 32 cm²
