Homework it’s too hard

Step-by-step explanation:

length=4×28=112 mm=11.2 cm

three centers form an equilateral triangle each side=2×28=56mm=5.6 cm

to find the height

h=√(5.6²-2.8²)=2.8√3

width=2.8+2.8√3+2.8=5.6+2.8√3=2.8(2+√3)

area=11.2×2.8(2+√3)≈117.03 7cm²≈117 cm²

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
