It is a trapezoid in which the non-parallel sides are of the same length and subtend equal angles with the base. It can be viewed as an isosceles triangle whose apex has been removed by a line parallel to its base.

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.

area of a trapezoid formula = 0.5 x (sum of bases) x height so 0.5 x 9 + 15 x 8 = 96
It is a trapezoid in which the non-parallel sides are of the same length and subtend equal angles with the base. It can be viewed as an isosceles triangle whose apex has been removed by a line parallel to its base.
Area = 1/2*(15+11)*7= 91 square units
The median of a trapezoid is one half of the sum of the two sides. So EF is 1/2 (12+18) = 1/2 (30) = 15.
