Apuzzle contains a triangular piece with a base of 3 in. and a height of 4 in. a manufacturer wants to make 80 puzzles. find the amount of wood used if each puzzle contains 20 triangular pieces.

I believe this question asks for the total amount of area of wood that is needed to make 80 puzzles.

The formula for area of triangle is given as:

A = (1 / 2) b h

where,

b = is the base of the triangle = 3 in

h = height of the triangle = 4 in

So calculating for area of 1 on triangle (A1):

A1 = (1 / 2) (3 in) (4 in)

A1 = (1 / 2) 12 in^2

A1 = 6 in^2

We are given that we are to make 80 puzzles and each puzzle has 20 triangles, therefore the total amount of triangles we need to make is:

n = 80 * 20

n = 1600

Therefore the total area needed (A) is:

A = A1 * n

A = 6 in^2 * 1600

A = 9,600 in^2

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
