Answer:
Line MN = 23 -3 -3 = 17
Middle Area = 17 * 17 = 289
Area of BOTH Ends = 17 * 3 = 51
TOTAL Area = 289 + 51 = 340
Explanation:
340 units squared
in the trapezoid, there is a square and an isosceles triangle
find the area of the square: 17×(23-6) =17×17 =289
find area of the triangle: 17×6 /2 =51
add the two together: 289 +51 =340
