Finding the Area of a Trapezoid in the Coordinate Plane
Oksanka [162]

The area of the trapezoid is 118 squre units

<h3>Area of a trapezoid</h3>

The formula for calculating the area of a trapezoid is expressed as:

  • A = 0.5(a+b)h
  • a  = AD = √20
  • b = BC = √80
  • height = h = √40

Substitute into the formula

A = 0.5(√1600)*√40

A = 0.5 * 40 * √40

A = 20√40

A = 118 squre units

Hence the area of the trapezoid is 118 squre units
