Answer:
Area = 160 sq cm
Perimeter = 67.31 cm
Step-by-step explanation:
Area of the figure = Area of rectangle with dimensions 16 cm and 12 cm - Area of the right triangle with base and height ecah 8 cm.
=16*12 - 1/2 * 8 *8
= 192 - 32
= 160 sq cm
GEF is a right triangle.
Therefore, by Pythagoras theorem:
Perimeter of the figure
= 12 + 16 + 12+4+8+11.31+4
= 67.31 cm

Answer:
A. rectangle, not a square.
Step-by-step explanation:
A right rectangular prism is a shape of a cube which is made up of 6 rectangular edges.
It has 4 vertical edges and 2 horizontal edges
The adjacent edges of the rectangular prism is at right angles
A plane intersects a right rectangular prism parallel to its base that is the parallel edges. The cross section formed by the plane would be the shape of the base as it is parallel to base and will intersect the the 4 vertical edges perpendicularly.
Thus, the shape of the cross section formed by the plane would be best described by a rectangle and not a square because the base is in the shape of a rectangle.
The figure representing the plane is shown below.
Answer:
Step-by-step explanation:
let a, b and c be the type of foods used in trail.
Example matrix combination for (1,1) is (a,a) is 0.5. Another Example for (1,2) is (a,b) is 0.25.
The diagonals are (a,a), (b,b) and (c,c) which means same food in two trails and its probability is 0.5. the rest would be 0.25
Therefore, stochastic matrix would have 3 by 3 matrix such as (a,a), (a,b) .... (c,c)
