The diagonal of a rectangle is 15 cm, and the perimeter is 38 cm. What is the area?
tigry1 [53]

Answer:

a² + b² = 15² = 225

P = 2a + 2b = 2(a + b) = 38

P² = 4(a + b)² = 38²

4(a² + 2ab + b²) = 1444

Substitute a² + b² with 225

4(2ab + 225) = 1444

2ab + 225 = 361

2ab = 136

ab = 68 cm²

qaws [65]

Answer:

2,200 students

Step-by-step explanation:

To find the number of students, create a proportion which is two equal ratios. Since the middle school and the high school are proportional then they have equal ratios.

\frac{students}{teachers}= \frac{900}{45}=\frac{x}{110}

Solve for x by cross multiplying by multiplying the numerator and denominator of each fraction.

900(110) = 45(x)

99,000=45x

2,200 = x
