4•4=16
12•5=60. That’s the answer
So the first thing we need to do is multiply 3*-5, since order of operations dictates it (PEMDAS)

Now, whenever we see a minus negative number, we can think of it as adding a positive number

Now we just add them together

23 is the answer
Solution:
<u>Note that:</u>
- Area of trapezoid = Area of triangle + Area of square = 575 m²
- Area of triangle = 32.5 m²
- Area of square = s²
<u>Finding the area of the square:</u>
- 32.5 + Area of square = 575 m²
- => Area of square = 575 - 32.5
- => Area of square = 542.5
- => s² = 542.5
- => s = √542.5 ≈ 23.29
The length of the square is 23.29 meters.
