I belive the answer is the 3rd one
You find the area of trapezium: 45
Then lower shape, triangle: 13.5
Then you add both:
B) 58.5 square feet:))
First of all we can draw a parallel line to divide the figure into a triangle and a rectangle as shown in the figure. To find the area of our rectangle, remember that the area of a rectangle is length times width, so

. Since we know for our figure that the length and width of our rectangle are 13cm and 6cm respectively, lets replace those values in our formula to get its area:


Similarly, the area of a triangle is one half times base times height, so

. Since we know that our base is 8cm and our height 6cm, lets replace those values in our equation to find the area of our triangle:


Now the only thing left is add our areas:

We can conclude that the correct answer is <span>
A. 102</span>
The answer is 40.
1000/25 will give you the new ratio
Simple way of thinking about it
25 enlisted men = 1 officer
1000enlisted men = X officer
Cross multiply (25 by X officer and the 1 officer by the 1000)
25x = 1000
X= 40.
35 has 4 divisors, hence two factor pairs: 1*35 and 5*7. Each corresponds to a set of perfect squares that differ by 35
One pair is ((35±1)/2)^2 = {17^2, 18^2} = {289, 324}
The other is ((7±5)/2)^2 = {1^2, 6^2} = {1, 36}
