The following octagon is formed by removing four congruent right triangles from a rectangle. What is the area of each triangle?
3241004551 [841]
Answer:
2 cm squared

Explanation:
The question asks for the area of each small triangle in the corners(meaning 1 triangle, not 4) as shown from the dotted lines. The area of a triangle is found by (base*height)/2.
Looking at the diagram, the triangle is 2 cm for both the base and height, and the hypotenuse is not labeled. Because it is a right triangle, 2 cm is also the height(the height is defined as an altitude from the tip of the triangle to the base using a right angle). So, height=2 and base=2.
Plug these numbers into the formula bh/2.
bh/2=?
(2)(2)/2=?
4/2=?
2=?
Each triangle has an area of 2 cm squared.

A rectangle is (x+10)ft by (x+4)ft. If a square of length xft on a side is cut from the rectangle, represent the remaining area
Andrei [34K]

Answer: A(x)=14x+40

Step-by-step explanation:

Given : The dimension of a rectangle is  (x+10)ft. by (x+4)ft.

Then, Area of rectangle will be :-

A_1(x)=(x+10)\times(x+4)=x^2+(10+4)x+40\\\\\Rightarrow\ A_1(x)=x^2+14x+40

If a square of length xft on a side is cut from the rectangle, then the area of the square :-

A_2(x)=x^2

Now, the remaining area in the form of a polynomial function A(x) will be :-

A(x)=A_1(x)-A_2(x)\\\\=x^2+14x+40-x^2=14x+40

Hence, the  remaining area in the form of a polynomial function A(x) will be :-

A(x)=14x+40
