<h3>
Answer: 297 square cm</h3>
=============================================
Work Shown:
Break up the figure as shown in the diagram below.
A rectangle and trapezoid form
-------------
Area of rectangle = base*height = 9*15 = 135 cm^2
Area of trapezoid = (1/2)*(b1+b2)*h = (1/2)*(18+9)*12 = 162 cm^2
total area = (area of rectangle)+(area of trapezoid)
total area = (135) + (162)
total area = 297 square cm
Answer=Order of operations
The order of operations (which we use PEMDAS to help us remember) tells you which operation to do first.
Use the Pythagorean theorem: a² + b² = c²
c = hypotenuse (which means) = 53
a and b are equal to the side length
So a = 21.
Use the formula and solve.
21² + b² = 53²
441 + b² = 2809
b² = 2368
b = 48.66210024238575 or 8√37
For this case, the first thing to do is find the scale factor.
We have then that for the length the scale factor is:
Then, as the scale factor is the same, then the new width is given by:
Answer:
The new width of the field is:
w = 22.5 yards
