Answer:
5
Step-by-step explanation:
let the width be x and length be 6x
Now,
perimeter of rectangle=70
2(l+b)=70
2(6x+x)=70
12x+2x=70
14x=70
x=70/14
x=5
12.52 in.
Area of square(A)=157in^2
length of square (l)=?
we know,
A=l^2
or,sqrt 157=l
12.52 in=l
There are many possibilities. An example is .
1)72=-8-5n
+8 +8
2)80=-5n
/-5 /-5
3)-16=n
