Let us find the area of the triangle first.
6 x 8 / 2 = 24 ft²
Now we can do the semi circle. Note that it is a semi circle and not a circle.
1/2π(4²) = 8π = 25.12 ft²
Add the areas up to find the area for the figure.
24+25.12 = 49.12 ft²
Okay, ask yourself this : how many times does 6 goes into 30?
6 and 1 = 6
6 and 2 = 12
6 and 3 = 18
6 and 4 = 24
6 and 5 = 30
6 goes into 30 a number of 5 times. And so that means that :
60 and 1 make 60.
60 and 2 make 120
60 and 3 make 180.
60 and 4 make 240
60 and 5 make 300
FIVE (5) groups of 60 make 300.
The answer is "The empty square has a side length of 10 and an area of 100 square units"
