Answer:

Step-by-step explanation:
The window consists of a large square and 4 smaller triangles on the outside. The side length of this square is marked as 10, and therefore the area of this square is
.
The area of a triangle is given by
. Since the problem states that the overlapping squares are congruent, both legs of the triangle will be
and intersect at a
angle.
Thus, the sum of all four triangles is
.
Therefore, the area of the window is:

It should be |-80+15|=65 units because absolute value makes it positive.
<span>The equation you start with is the given equation.
x/6 + 2 = 15 a. Given
The next step in solving this equation is subtracting 2 from both sides.
x/6 = 13 b. Subtraction Property of Equality
Lastly, to cancel out the denominator, multiply both sides of the equation by 6.
x = 78 c. Multiplication Property of Equality

Step-by-step explanation:
The width of rectangle is the diameter of the semi-circle part
Area of one semicircle is given by 
Total area of semi circle will be 
Substituting 74 m for d and
as 3.14 we obtain
Total area semi-circle=
Area of rectangle is given by the product of length and width
Rectangular area=
Total area of rectangular and semi-circles will be

Therefore, area of training field is
