Answer:
Explanation:
To find the area you first split the shape in two; a triangle and a rectangle.
Since the opposite sides of a rectangle are always equal we can assume that the right side of the rectangle is also 130m and the top is also 80m. This would mean that 80 meters from the 230 meters that is given as the measurement for the top of the entire shape would be for the rectangle. This also means that the remaining 150 meters would be the measurement for the height of the triangle.
Also assuming that the right side of the rectangle is 130 meters we can then subtract the 60 meters that was given in the question *from* the 130 meters to find the measurement for the base of the triangle, which would be 70 meters.
Now we add the area of the rectangle and the triangle to find the area of the entire shape.
area of triangle: 1/2 base x height
1/2(70) x 150 = 5250
area of rectangle: length x width
130 x 80 = 10,400
area of triangle + area of rectangle
5250+10400 = 15650
