Answer:
The first side= 9 inches
The second side=12 inches
The third side=7 inches
Step-by-step explanation:
Lets make expressions to represent each of the three sides of the triangle.
If we start with the second side and say its length is x inches, then the first side becomes (x-3) inches.
The third side is gotten by subtracting 2 inches from this first side. Then its expression becomes: (x-3)-2 which can be simplified to x-5 inches.
The perimeter of a triangle is found by adding the lengths of the three sides of the triangle, thus, we add the three expressions and then equate the result to the numerical value of the perimeter.
x+(x-3)+x-5=28
3x-8=28
collecting like terms together we get:
3x=36
x=12 inches
Therefore, the first side (x-3) we substitute for x so 12-3=9
second side x is 12
the third side x-5 gives 12-5=7

Step-by-step explanation:
Answer: The two dimensions are the same in the triangles as they were in the rectangle.
Step-by-step explanation:
Height of a triangle is the perpendicular distance from the one vertex of the triangle to the one side of the triangle( that side is called base of the triangle).
Let the length of the given rectangle is l unit and width of the rectangle is b unit,
When the rectangle is cut along its diagonal,
Then we found two right triangles,
In which both having dimensions,
height = b and base = l,
Thus, the dimension of the triangles are same as the rectangles.
⇒ First option is correct.
