Answer:
336 feet²
Step-by-step explanation:
If we have a rectangle that is 30 by 20 feet, that means the area of that rectangle would be 20 × 30 feet squared, which is 600 ft².
If there is a 3 feet sidewalk surrounding it, that means that the end of the sidewalk will extend 3 feet extra around each side of plot. Since there are two ends to one side, that means an extra six feet is added on to each dimension. Therefore, 36 × 26 are the dimensions of the sidewalk+plot. 36 × 26 = 936 ft².
To find the area of the sidewalk itself, we subtract 600 ft² from 936 ft². This gets us with 336 ft².
Hope this helped!
Your answer would be A 1040.
Answer:
Complementary, X = 60 degrees
Step-by-step explanation:
Complementary = 90 degree angle
Supplementary = 180 degree angle
(x - 30) + x = 90
(60 - 30) + 60 = 90
30 + 60 = 90
4/9 is the simplest ratio......
