Answer:
y = 156(0.82)x
Step-by-step explanation:
Since it is decreasing by 18% you need to subtract .18 from b (which equals 1) and it gives you 0.82.
It should be 125 as
BC=100
and it's four times the length of AB then
100/4=25
then 100+25=125

Simple area working out:
Area of a triangle: L x W
———
2
Area of a square: L x W
17 (L) x 17 (H) = 289cm^2
289
——- = 144.5cm^2
2
There are 4 triangles so:
144.5 x the amount of triangles (4) = 578
Add everything together:
578 + 289 = 867
Answer: 867
