Answer:

the total distance is 56 cm

Step-by-step explanation:

Given that the area of the bulletin board is 196 cm^2

Based on this, the total distance around the bulletin board is

But before that we need to find out the side

As the area of square is

= side^2

196 = side^2

So side = 14

Now there are four sides, so the total distance is

= 4 × 14

= 56 cm

Hence, the total distance is 56 cm

1. = Step 1. Simplify Brackets and you get 12.5 - 31.5 Step 2. Simplify and you get -19&#10; which is your answer.

2. = Step 1. Simplify Brackets and you get -31.91-16.7 Step 2. Simplify and you get -48.61

3. = Step 1. Simplify Brackets and you get \frac{1}{6} - \frac{11}{12} + \frac{2}{3} Step 2. Simplify and you get - \frac{1}{12}

4. Step 1. = Simplify Brackets and you get 29-15.7-31.05 Step 2. Simplify and you get -17.75

What is the area of a triangle with vertices (3,0) (9,0) (7,6)
Nezavi [6.7K]

Answer:

The area of the triangle is of 21 units of area.

Step-by-step explanation:

The area of a triangle with three vertices (x_1,y_1),(x_2,y_2),(x_3,y_3) is given by the determinant of the following matrix:

A = \pm 0.5 \left|\begin{array}{ccc}x_1&y_1&1\\x_2&y_2&1\\1_3&y_3&1\end{array}\right|

In this question:

Vertices (3,0) (9,0) (7,6). So

A = \pm 0.5 \left|\begin{array}{ccc}3&0&1\\9&0&1\\7&7&1\end{array}\right|

A = \pm 0.5(3*0*1+0*1*7+1*9*7-0*7*1-0*9*1-3*1*7)

A = \pm 0.5*(63-21)

A = \pm 0.5*42 = 21

The area of the triangle is of 21 units of area.
