Given
square and add terms i.e.
Using identity
Answer:
<u>Area:</u> 10,000 yards
<u>Perimeter:</u> 410 yards
Step-by-step explanation:
<u>Area: To find area, multiply one side by the other</u>
80 * 125
10,000
Answer: 10,000 yards
<u>Perimeter: To find the perimeter, use the formula 2a + 2b </u>
2(80) + 2(125)
160 + 250
410
Answer: 410 yards
60 min = 1 hr
3/4 * 60 = mph (miles per hour)
3/4 * 60 = 45
The speed of the car in mph (miles per hour)
will be 45 mph
Answer = 45mph

First thing to do is to illustrate the problem, Since it was mentioned that work was along the way to training, the order is shown in the picture. Mary's home and workplace are nearer compared to her training center. It is also mentioned that the distance between work and home, denoted as x, is 2/3 of the total distance from home to training. The total distance is (x + 2.5). Thus,
x = 2/3(x+2.5)
x = 2/3 x + 5/3
1/3 x = 5/3
x = 5 km
Thus, the distance from home to work is 5 km. This means that Mary has to walk this distance twice to return home to get her shoes. Then, she will travel again the total distance of 5+2.5 = 7.5 km to get to her training center. So,
Total distance = 2(5km) + 7.5 km
Total distance = 17.5 km
