Answer:
180 ft²
Step-by-step explanation:
The figure is composed of 2 triangles and a rectangle between them
Calculate area of triangle on left
A = bh ( b is the base and h the perpendicular height ), thus
A = × 9 × 6 = 4.5 × 6 = 27 ft²
Area of rectangle = 12 × 9 = 108 ft²
Calculate the area of the triangle on the right
A = × 9 × 10 = 4.5 × 10 = 45 ft²
area of composite figure = 27 + 108 + 45 = 180 ft²
Answer:
(3, -2)
Step-by-step explanation:
The <em>midpoint</em> of two points is half-way between the x-values and the y-values.
The formula is
M = ((x₁ + x₂)/2, (y₁ + y₂)/2)
For the points (5,-5) and (1,1),
Half way between the x values is
(x₁ + x₂)/2 = (5 + 1) /2 = 6/2 = 3
Half way between the y values is
(y₁ + y₂)/2= (-5 + 1)/2 = -4/2 = -2
M = (3, -2)
The graph below shows your two points at (5,-5) and (1,1) and the mid-point at (3, -2).
