Gary’s playing the role of the greek god zeus in a school play he carries a lightning bolt cut from plywood its dimensions are shown in the figure what is the area of the wooden cutout of the lightning bolt

As the figure is not attached, I have attached the figure using the link- https://cdn.ple.platoweb.com/EdAssets/6764fbd04e1f4014be049f2831fd4e8c?ts=635356393812430000

Area is 30 square inches.

Step-by-step explanation:

Given:

The wooden cutout of the lightning bolt consists of 2 right angled triangles with the legs being 10 inches and 3 inches.

The area of this lightning bolt will be equal to the sum of the areas of the two right angled triangles.

The area of a triangle of base 'b' and height 'h' is given as:

Here, . Plug in solve for area of one of the triangles.

Therefore, area of the right angled triangle is:

Now, the two right angled triangles are congruent. So, total area is twice the area of one of the triangle.

Therefore, total area of the lightning bolt is in².

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
