In this polygon, all angles are right angles.
krek1111 [17]

The area of the given polygon is  1830 cm².

<h3>What is a polygon?</h3>

A polygon is a closed more than two-sided and can be made up of a finite number of straight line segments and is a type of planar figure in geometry.

Each line of the polygonal circuit's segments is referred to as its edges or sides.

We know the area of a square is (side)² and the area of a rectangle is (length×width).

From the given diagram we can think of this polygon as a square having a side length of 46cm and a rectangle having a width (30 - 14) = 16cm and length 21cm, And subtract the area of the rectangle from the area of the square which is,

= (46×46) cm² - (16×21) cm².

= (2166 - 336) cm².

= 1830 cm².

Rút gọn (x-4) (x-3) -x(x+5) +82
WINSTONCH [101]

Answer:

-12x + 94

Step-by-step explanation:

Simplify:

\left(x-4\right)\left(x-3\right)-x\left(x+5\right)+82

=x^2-7x+12-x\left(x+5\right)+82

=x^2-7x+12-x^2-5x+82

=x^2-x^2-7x-5x+12+82

=-7x-5x+12+82

=-7x-5x+94

=-12x+94

A rectangular prism has a volume of 378 cubic inches the area of the base is 42 square inches what is the height
barxatty [35]

Answer:

9 inches.

Step-by-step explanation:

The formula for the volume of a rectangular prism is base x height.  So if the volume is 378, and the base is 42, you would use the equation 378/42 to find the height. 378/42 is 9.  Therefore, the height is 9 inches.
