Gary is 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?
15
30
45
60

30  square inches.

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:

20s=m

Step-by-step explanation:

I really don't understand it that well but all that I can is that s can represent students that went on the trip, and each student's ticket cost is 20$, so 20*s=20s, but we are taking m as the total money collected, so we can end up saying that 20s=m, hope u understood :)
