Compose the trapezoid into a parallelogram what is the area of the trapezoid The area of a trapezoid found by composing a trapezoid into a parallelogram is (. )ft squared

9514 1404 393

  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

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

so then what are you asking?
