Find the area and perimeter of the given rectangle.

Mathematics
1 answer:
jeka943 years ago
7 0

Answer:

The Area is 99 units², while the perimeter is 40 units

Step-by-step explanation:

Area can be found by multiplying the length of the rectangle by the width of the rectangle. Counting the boxes on the side gives you 11 horizontally and 9 vertically. Multiplying these two gives you an area of 99. The measurement is  in units because there is no given unit of measurement such as inches, feet, or meters. Area is always squared which is why there is a ² after units.

Perimeter can be found by adding all 4 sides together. Counting the boxes gives you 11 + 11 + 9 + 9. This gives you a perimeter of 40.  The measurement is in units because there is no given unit of measurement such as inches, feet, or meters. Perimeter is not squared like area.

Point A is at (6,-6) and point C is at(-6,-2). find the coordinates of B on AC so that AB= 3/4AC.
loris [4]

Answer:

B(-6, 0)

Step-by-step explanation:

You want to find B such that ...

(B -A) = (3/4)(C -A) . . . . the required distance relation

4(B -A) = 3(C -A) . . . . . . multiply by 4

4B = 3C +A . . . . . . . . . . add 4A, simplify

Now, we can solve for B and substitute the given coordinates:

B = (3C +A)/4 = (3(-6, -2) +(-6, 6))/4 = (-24, 0)/4 = (-6, 0)

The coordinates of point B are (-6, 0).

Hope it helped u if yes mark me BRAINLIEST!

the sum of kate's age and her mother's age is 52. Kates mother is 20 years older than kate. how old is each
Anna35 [415]
<span>The sum of Kate age and her mother's age is 52, so 
K + M = 52 
Kate's mother is 20 years older then Kate, so 
M = 20 + K 
How old is each person? 
Since M = 20 + K, substitute it into the first equation, that is, replace M with 20 + K 

So, K + (20 + K) = 52 
K + 20 + K = 52 
2K + 20 = 52 
Subtract 20 from both sides: 
2K = 52 - 20 
2K = 32 
divide both sides by 2 to get 
K = 16 
Now we can find M, since M = 20 + K = 20 + 16 = 36 
Kate is 16 years old and her mother is 36 years old.
Hope this helps!!1</span>
