The only Pythagorean triple with legs in arithmetic sequence is the 3-4-5 triangle.
The sides should be 3 cm, 4 cm, 5 cm.
Answer:
The area of the backyard is <u>944 ft²</u>.
Step-by-step explanation:
Given:
a = 23 ft, b = 32 ft, and c = 36 ft.
Now, to find the area of the backyard.
So, we get a rectangle and a triangle if we divide the figure.
Thus, a rectangle and a triangle as shown in below figure.
So, a = 23 ft, b = 32 ft, c = 36 ft, and d = 32 ft.
And, e = 36 - 23 = 13 ft.
Now, to get the area of the rectangle we put formula:
Area = 

Now, to get the area of the triangle we put formula:




So, to get the total area of backyard we add both the areas of the rectangle and triangle:


Therefore, the area of the backyard is 944 ft².
Answer:
53/8 or 6.625
Step-by-step explanation:
10 + (-3 3/8)
Convert everything to a fraction having the same denominator.
<u>-3 3/8</u>
-24/3 - 3/8
-27/8
<u>10</u>
80/8
Combine: (80/8 - 27/8) = 53/8 or 6.625
Any number can be increased if the percentage is more than 100%
for instance
120% of 10
120*10/100 =12
here the number 10 is increased to 12
