Perimeter = 18 miles
Perimeter = 2a + 2b
2a + 2b = 18
a = ?
b = 7
18 = 2a + 2*7
18 = 2a + 14
2a = 18 - 14
2a = 4
a = 2
Area = a * b
Area = 2 * 7 = 14 miles2
X = 5
AE and congruent to EC
Unfortunately, you inadvertently cut off the instructions for this problem when you photographed it. Could you try again, making certain to include the instructions?
Let me guess: perhaps the instructions are 1) determine the slope of the line passing through the given points, or 2) write the equation of the line passing through the given points.
Answer:
D. diagonal = 20.10 cm
Step-by-step explanation:
Find the bottom diagonal using the length and width.
diagonal² = 8² + 12²
diagonal = √64+144
diagonal = √208
diagonal = 4√13
---------------------------------------------------------------------------------------------------------
Find diagonal of the rectangular solid:
diagonal² = (4√13)² + 14²
diagonal² = 208 + 196
diagonal = √404
diagonal = 20.10 cm
