The area of a rectangle is 55.5 square inches. The height of the rectangle is 15 inches. What is the length of the base of the rectangle in inches?
Responses
A 40.5 in40.5 in
B 3.7 in3.7 in
C 832.5 in832.5 in
D 6.5 in6.5 in
D (6.5 in)
Explanation:
We can use the formula for the area of a rectangle: A = l x w (length times width). We know that the area is 55.5 and the height is 15, so we can plug in these values and solve for the length:
55.5 = l x 15
Divide both sides by 15:
l = 55.5 ÷ 15
l ≈ 3.7
So the length of the base of the rectangle is approximately 3.7 inches.

What is the value of 5/6 divided by 15/16
To divide two fractions, we multiply the first fraction by the reciprocal of the second fraction.
So,
(5/6) ÷ (15/16) = (5/6) x (16/15)
We can simplify by canceling out the common factor of 5:
= (1/6) x (16/3)
= 16/18
We can simplify again by finding a common factor of 2:
= 8/9
Therefore,
5/6 ÷ 15/16 = 8/9
