For this case we have that by definition, if we draw the diagonal of a square two rectangular triangles are formed. If the diagonal measures "x", then the Pythagorean theorem is fulfilled:
Where:
l: It's the side of the square.
We know that the area of a square is given by:
So, the area is:
Answer:
Answer:
eleven and three hundredths.
Step-by-step explanation:
Since we know that the area is 100 and we are dealing with a square, that means that all sides are equal. We know that the sides are all 10 because 10*10= 100.
To find the perimeter, we add up all the sides: 10+10+10+10 = 40m
Answer:
15
Step-by-step explanation:
800 = 120
100 = x (number we have to find)
800x = 12000
x = 12000 ÷ 800
x = 15
