Answer: 872
10 times 16 = 160
12vtimes 10 = 120
20 times 20 = 400
12 times 16 = 192
*with the area of triangles, you have to divide your number by 2, but there is 2 triangles, so 192, instead of 96*
Step-by-step explanation:
Find the distance between each
between points (x1,y1) and (x2,y2)
D=

find and verify that
BC=CD=DE=EB
so
BC=

=5√2
CD=

=5√2
DE=

=5√2
EB=

=5√2
true
A straight line has the same gradient all along its length. The gradient equals vertical rise over horizontal distance. It does not matter which triangle you use.
For large triangle it equals 2/8 or 1/4 for smaller one. Both equal 1/4 (last statement)
