15 The formula for the area of a trapezoid is A The height, h, of the trapezoid may be expressed as (1) 2A – b₁ – b₂ (2) 2A - b₁ b₂ (3) (4) A-b₁ b₂ – 2 2A b₁+ b₂ = // (b₁ + b₂)h.

Use what you have learned in Calculus II to find the area of the triangle made up of the points (0,0),(1,0) and (1/2,√3/2 ).Then, multiply your answer by 6 to get the area of the hexagon. Is this a close approximation of π? Why or why not?

FGHI is a trapezium with dimensions as shown in the diagram below. If P is a point on IH such that PI = GF, calculate: (b) the diagonal GI (d) area of FGPI %3D (a) ZGHP (c) ZGFI (e) area of the shape IFGH. 12 cm H. 7 cm 6 cm F 8 cm G.

High school students used Pick's theorem to determine the area of leaves, which biologists need to do. The formula is A = + I – 1, where b is the number of boundary points and I is the number of 2 interior points in a figure that has been traced on Geoboard Dot Paper.t (a) Use your knowledge of triangles and other shapes to find the area (in square units) of the figure on the left pictured above. square units (b) Calculate the area (in square units) of the figure on the left pictured above using Pick's theorem. square units (c) Determine the area (in square units) of the leaf on the right pictured above using Pick's theorem. (Round your answer to one decimal place.) square units
