The three interior angles of every triangle always add up to 180 degrees

Basic Geometry Formulas

Triangle

• Area = ½ × Base × Height
• Perimeter = a + b + c
• Sum of angles = 180°

Rectangle

• Area = Length × Width
• Perimeter = 2(Length + Width)

Square

• Area = Side²
• Perimeter = 4 × Side

Circle

• Area = πr²
• Circumference = 2πr

Triangle angle

• Interior angles = 180°

Explanation

A completes the work in 12 days.

So, A's 1-day work:

1/12

B completes the work in 24 days.

So, B's 1-day work:

1/24

Together, their 1-day work:

1/12 + 1/24  

LCM of 12 and 24 = 24:

 2/24 + 1/24  

= 3/24  

= 1/8  

Therefore, they will complete the whole work in:

8 days
