Answer:

3 1/2

Step-by-step explanation:

-3 1/6+6 2/3

We need to get a common denominator of 6

-3 1/6 + 6 2/3 *2/2

-3 1/6 + 6 4/6

Since the signs are different, we subtract and take the sign of the larger number

6 4/6 - 3 1/6 = 3 3/6 = 3 1/2

The sign of the larger number was positive so the answer is positive

3 1/2

Aneli [31]
There’s probably an easier way to do it like with the equation to find the area of a trapezoid but i did it this way bc it’s easier for me

i split the trapezoid into a triangle and a square
with the pythagorean theorem i found the missing side length to find the area of the square (length X width)
then found the area of the triangle (base X height divided by 2)

THE ANSWER IS 68.9 CM
