Answer:
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.
