Area of a rectangle is 27 cm²
Given:
Perimeter of a rectangle = 24 cm
Length = 3x
Width = x
p = 2(l + w)
24 = 2(3x + x)
24 = 6x + 2x
24 = 8x
24/8 = x
3 = x
Width = 3 cm ; Length = 3x = 3(3) = 9 cm
Area = length * width
= 9cm * 3 cm
Area = 27 cm²
Answer:
fraction dude
As you might remember, a rational number is any number that can be written as a fraction pq. Here the numerator and denominator are both integers, and q≠0.
Step-by-step explanation:

You can use the Pythagoras theorem for this since a right triangle is formed.
C = 12
A = 4
B = x
Input values:
So, about 11ft.
Answer:
0.0455
Step-by-step explanation:
<u>The formula for calculator probability is
</u>
# of favorable outcomes / # of possible outcomes
<u>The total number of marbles in the bag: </u>
7+3+2=12
<u>Probability of the first marble being blue:</u>
3/12
<u>Probability of the second marble being blue:</u>
2/11 -- 2 because only 2 blue marbles left after drawing the first one out, 11 because after taking the first marble out, we have 11 marbles left in the bag
<u>Formula for both events happening:</u>
p(A and B) = p(A) * p(B)
In this problem,
A = first one blue
B = second one blue
<u>Probability that if two marbles are drawn out of the bag, both are blue:</u>
3/12 x 2/11 = 0.045454
<u>Rounded answer:</u>
0.0455 (or 4.55%)
Assuming that the given numbers for the perimeter and area of the rectangles are 9 cm and 12 cm.
Then the perimeter being l + w becomes 3 + 3 = 9 cm for the first; 6 + 6 = 12 cm for the second.
Areas would be (3)^2 and (3.5)^2
