We have two right triangles and three different rectangles.
The formula of an area of a right triangle:
l₁, l₂ - legs
We have l₁ = 20cm and l₂ = 21cm. Substitute:
The formula of an area of a rectangle:
l - length
w - width
We have:
rectangle #1: l = 22cm, w = 29cm
rectangle #2: l = 22cm, w = 21cm
rectangle #3: l = 22cm, w = 20cm
The total Surface Area of the triangular prism:

Step-by-step explanation:
I think D but don’t take my word for it
Answer:
D
Step-by-step explanation:
Firstly let's see definition of Rational numbers ,
<u>Rational</u><u> numbers</u><u> </u><u>:</u><u>-</u><u> </u>
- The number in the form of p/ q where p and q are integers and q is not equal to zero is called a Rational number .
From the options , look at option D ,its
→ √400
→ √{20²}
→ 20
<h3>
Hence option D is correct.</h3>
