The perimeter of an isosceles triangle is 36. One side is 10. What are the possible lengths of the base? Find the area of the tr
Archy [21]

Answer:

\boxed{\textbf{10 and 16; 60}}

Step-by-step explanation:

1. Length of base

There are two possibilities

(a) Base = 10

Then we have a triangle as in Fig. 1.

\begin{array}{rcl}p & = & 2x + 10\\36 & = & 2x + 10\\26 & = & 2x\\x & = & \mathbf{13}\\\end{array}

(b) Side = 10

Then we have a triangle as in Fig. 2.

\begin{array}{rcl}p & = & x + 20\\36 & = & x + 20\\x & = & \mathbf{16}\\\end{array}\\\text{The possible lengths of the base are $\boxed{\textbf{10 and 16}}$}

2. Area of triangle

One way to find the area of the triangle is to use Heron's formula:

A = \sqrt{s(s - a)(s - b)(s - c)}

where s is the semiperimeter.

Each triangle has the same perimeter, so it also has the same semiperimeter and therefore the same area.

s = p/2 = 36/2 = 18

\begin{array}{rcl}A & = & \sqrt{18(18 - 13)(18 - 13)(18 - 10)}\\& = & \sqrt{18\times 5 \times 5 \times 8}\\& = & \sqrt{3600}\\& = & \mathbf{60}\\\end{array}\\\text{The area of each triangle is $\boxed{\mathbf{60}}$}

the length of the rectangle is twice its width. write and solve a system of linear equations to find the length L and width W of
xz_007 [3.2K]

Answer:

2 ( m + 2 m)  = 36 is the required linear equation

Length of the rectangle is 12 ft and width =  6 ft

Step-by-step explanation:

Let the width of the rectangle = m ft.

So, the length of the rectangle = 2m  ft.

Perimeter  of rectangle = 36 ft

Now, PERIMETER OF THE RECTANGLE = 2(LENGTH + WIDTH)

⇒2 ( m + 2m)  = 36

or, 2 x 3m  = 36

⇒ 6m  = 36  , or m  = 36/6

⇒ m  =6 ft

So, the Width of the rectangle;  =  m = 6 ft

and the Length of the rectangle  = 2 m  = 2 x 6 =  12 ft.
