the area is 788.5
the formula to find a trapezoid is 2h(b₁+b)
to substitute that, i would be 2(19)(55+28)
the answer to that is 788.5
the perimeter is 125.
to find the perimeter, u need o add all the sides to get the perimeter.
the formula is
P=a+b+c+d
to substitute that it would be 55+28+21+21.
the answer to that is 125.
