The length of a rectangle is 4 less than twice the width. If the perimeter of the rectangle is 130, find the length of the recta
Alchen [17]

Answer:

Let L be the length of the rectangle and w be the width of the rectangle.

"The lenght of a rectangle is one less than twice the width" means L=2W-1

Using perimeter formula of a rectangle which is P=2(L+W) you have:

P=2(L+W)

130=2(2W-1+W)

Solve equation above to find W

130=2(3W-1)

130=6W-2

130+2=6W

132=6W

W=22

From here you find L=2W-1=2x22-1=43

Only thing left is to find area A=LxW

Please help <br> The diagram shows a 5ft student standing near a tree
Novosadov [1.4K]

Answer:

25 ft

Step-by-step explanation:

The diagram shows two triangles that are similar.  Similar triangles have equal angles and sides that are proportional to each other.  Since the base of each triangle is given, we can find the proportion of the sides:

\frac{smaller}{larger}=\frac{8}{40}=\frac{1}{5}

Given the ratio of the smaller to larger triangle, we can set up a proportion to find the missing height of the larger triangle:

\frac{1}{5}=\frac{5}{x}, where 'x' represent the height of the tree

cross-multiply:  x = (5)(5) or 25 ft
