Given : Bev has to cut her grandma's grass this weekend
Six-sided polygon that includes two isosceles right triangles, one with height and base of 15 feet, the other height and base of 4 feet, and one rectangle measuring 25 feet by 4 feet.
To Find : Area of Polygon
Solution:
Area of triangle = (1/2) bh
= (1/2) * 15 * 15
= 112.5 sq feet
= (1/2) * 4 * 4
= 8 sq feet
Area of rectangle = 25 x 4 = 100 sq feet
Total area =112.5 + 8 + 100
= 220.5 sq feet
Area of Polygon = 220.5 sq feet

PLEASE HELP WILL GIVE BRAINLIEST
Answer:
Step-by-step explanation:
The graph of a quadratic function is a U-shaped curve called a parabola. One important feature of the graph is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value. In either case, the vertex is a turning point on the graph. The graph is also symmetric with a vertical line drawn through the vertex, called the axis of symmetry. These features are illustrated in (Figure).
Graph of a parabola showing where the x and y intercepts, vertex, and axis of symmetry are.
The y-intercept is the point at which the parabola crosses the y-axis. The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts represent the zeros, or roots, of the quadratic function, the values of x
