Gamma rays have neither mass nor charge.
Answer:
2(1/2 x 5 x 12) + (13 x 2) + (12 x 2) + (5 x 2)
Step-by-step explanation:
You must first find the area of the two triangles, and then find the area of the remaining rectangles.
Applying it's formula, the area of the given triangle is of 30 centimeters squared, that is, 30 cm².
<h3>What is the area of a triangle?</h3>
The area of a triangle of base b and height h is given by half the multiplication of these measures, that is:
A = 0.5bh.
In this problem, we have that b = 12 cm, h = 5 cm, hence:
A = 0.5 x 12 cm x 5 cm = 30 cm².
