Find the area of triangle DEF with vertices D(-1,2), E(3,-2) and F(-2,-2).*
Veronika [31]

Answer:

<em>The area of the triangle DEF is 10.</em>

Step-by-step explanation:

<u>Area of a Triangle:</u>

A triangle of base B and height H (both must be perpendicular) has an area of:

\displaystyle A=\frac{BH}{2}

The image below shows the triangle formed by the points DEF. It's important to notice the points E and F lie on the same horizontal line because they both have the same y-coordinate.

This fact simplifies the calculations since we can easily compute the length the of base as the difference of their x-coordinates:

B=3-(-2)=3+2=5

Being the base of a horizontal line, the height of the triangle can be calculated as the difference of y-coordinates of D and the height of that line.

H=2-(-2)=4

With these two values, we calculate the area:

\displaystyle A=\frac{5*4}{2}=10

The area of the triangle DEF is 10.

Sholpan [36]
We know that
circumference=2*pi*r
for r=7 in
circumference=2*pi*7------> 14*pi in

if 360° (full circle)  has a length of------------ 14*pi in
 135°-----------------------------> x
x=135*14*pi/360----------> x=5.25*pi in--------> 16.49 in

the answer is
5.25*pi in  or 16.49 in
