Hello there! 6^1 is not a perfect square. It's basically it's own number and 6 is not a perfect square. Therefore, A is out. 6^3 (216) is cubed, not squared, so C is out as well. Just by looking at the exponents, 6^2 is squared and 36 is a perfect square, so the answer is B: 6^2.
Length of the rectangle
=
15
feet
Breadth of the rectangle
=
30
feet.
Explanation:
Let the breadth of the rectangle
=
x
So, the length of the rectangle
=
2
×
x
The perimeter given
=
90
feet
As per the formula for perimeter of a rectangle
Perimeter
=
2
×
(length + breadth )
90
=
2
×
(
x
+
2
x
)
90
=
2
×
(
3
x
)
90
=
6
x
x
=
90
6
x
=
15
So the length of the rectangle
=
15
feet, breadth of the rectangle
=
30
feet.
