Answer:
Area of trapezoid = 19.84 in^2
Explanation:
Area of trapezoid = (b1+b2)/2 * Height
to find the height we have to use the Pythagorean formula for the left triangle
we sub the values in the formula
Y =
which the height of the triangle
now we sub the values in the trapezoid formula
Area of trapezoid = (5+10)/2 * sqrt{7}
Area of trapezoid = 19.84 in^2
