The formula for calculating the area of a trapezoid is expressed as A = 0.5(a+b)h. The given area of the trapezoid is 1398.9 square inches
Area of a trapezoid
The formula for calculating the area of a trapezoid is expressed as:
A = 0.5(a+b)h
Given the following parameters
a = 10m = 393.7in
b = 6in
h = 7in
Substitute
A = 0.5(393.7 + 6) * 7
A = 0.5 * 399.7 7
A = 1398.9 square inches
Hence the given area of the trapezoid is 1398.9 square inches
