Answer:
3:√15 in
4: 5√3 m
5: 49 m²
6: 1.69 in²
Step-by-step explanation:
To find the area of a square you take the lenght and multiply it by its width
The special thing about a square is that all sides are equal meaning length=width so we only need one side to get all the information we need
For this question x will be the side of a square
3: Area= x²
15=x²
√15=x
4: same deal as 3
75=x²
√75=5√3
5: This is even easier then the other two
we adjust our equation to look like the following
area=side²
so area=7²=49
49
6: same deal as before
1.3²=1.69
