Answer:
Step-by-step explanation:
FE=4+4=8
Altitude=3+3=6
area=1/2×FE×6=1/2×8×6=24 sq. units.
or
area=1/2×
I 1 3|
|-4 -3|
| 4 -3|
| 1 3|
=1/2[(-3+12)+(12+12)+(12+3)]
=1/2[9+24+15]
=1/2[48]
=24 sq. units
The speed of the airplane = 2951 / 6.5 = 454 mph

Step-by-step explanation:
Divide the polygon into 5 triangles by using each side as a base and joining the vertices of the polygon to a common point (for example, the centre). If the polygon is regular the angle at the vertex of each triangle is 360/5=72 degrees, so you have 5 isosceles triangles of equal area. Find the area of one and multiply by 5 to get the total area.multiply 5 times the lenght of oneside
