Answer:
26 square feet
Step-by-step explanation:
When two of the trapezoids are combined to make a parallelogram, the height remains the same (4 ft), but the width is the sum of the base lengths, 10 ft + 3 ft = 13 ft.
The area of the combined trapezoids is ...
A = bh = (13 ft)(4 ft) = 52 ft^2
The area of one trapezoid is half that, so is ...
A = (52 ft^2)/2 = 26 ft^2 . . . . area of the trapezoid
