Answer:
Step-by-step explanation:
The perimeter is 28".
The total length of three sides of the square = 28-5-5 = 18", so the side length of the square is 18/3 = 6".
The area of the triangle is ½(6)(4) = 12 square inches.
The area of the square is 6² = 36 square inches.
Total area = 12+36 = 48 square inches.
Answer:
60 professors and 168 lecturers
Step-by-step explanation:
What you have is a 2 equations system with 2 unknown variables.
Let X be the number of professors and Y be the number of lecturers. As the total of both is 228:
X + Y = 228
Then, as there are 5 professors for every 14 lecturers:
5 X = 14 Y or X = (14/5) Y
Replacing this last value of X on the first equation:
(14/5) Y + Y = 228
(14/5) Y + (5/5) Y = 228
(19/5) Y = 228
Y = 228 * (5/19)
Y = (228*5)/19
Y = 1140 / 19
Y = 60
Then we can find X:
X = (14/5) Y = (14/5) * 60 = 168
X = 168
