What makes a square a square <br> why isn't a rectangle?
Lilit [14]
A square is a geometrical figure that has 4 congruent sides and angles. This means all side lengths and angles are the same.

A rectangle is a geometrical figure that has 4 similar sides but are not the same length. However, a rectangle does have congruent angles. A rectangle has 2 sides that are double the other 2 sides, in which both of each (length & width) have the same measurement.

I hope this helps!

A bulletin board has a perimeter of 200 inches. Which expression expresses the area A(w) of the bulletin board as a function of
mr Goodwill [35]

Answer:

area A(w) of the bulletin board as a function of its width, w =[100-w]*w= 100w-w^{2}

Step-by-step explanation:

  • let, the shape of the bulletin board is a rectangle,
  • then the perimeter of it = sum of all sides

= 2[length+width] = 2[l+w]

(let l: length, w : width )

  • so, 200 = 2[l+w]

100= l+w ( dividing both the sides by 2)

so, l= 100-w

  • area = length*width=l*w=[100-w]*w
  • therefore,area A(w) of the bulletin board as a function of its width, w =[100-w]*w= 100w-w^{2}

Find the volume of the following
Nadusha1986 [10]

Given:

A prism with right triangular base.

Base of triangle = 6 ft

Height of triangle = 8 ft

Height of prism = 7

To find:

The volume of the given prism.

Solution:

The volume of prism is:

V=Bh             ...(i)

Where, B is the base area and h is the height of the prism.

In the given figure, the base of the prism is a right angle triangle with legs 6 ft and 8 ft. So, the area of the base is:

B=\dfrac{1}{2}\times base\times height

B=\dfrac{1}{2}\times 6\times 8

B=\dfrac{48}{2}

B=24

Substituting B=24,\ h=7 in (i), we get

V=24\times 7

V=168

Therefore, the volume of the prism is 168 cubic ft.
