Answer:
4√2 + 2√10
Step-by-step explanation:
Finding the perimeter here involves finding three point-to-point distances and then adding them up.
From (2, 2) to (6, -2) we have a change in x of 4 and a change in y of -4. We use the Pythagorean Theorem to determine the distance, which is the hypotenuse of a right triangle:
√( [4]² + [-4]² ) = 4√2. This is the length of the side connecting (2, 2) and (6, -2).
From (6, -2) to (5, 1), the distance is √( [-1]² + 3² ), or √10.
From (5, 1) to (2, 2), the distance is √( [-3]² + 1² ), or √10.
The perimeter is the sum of these three distances and is:
4√2 + √10 + √10, or 4√2 + 2√10
Answer:
Step-by-step explanation:
<u>Using Pythagorean Theorem first to find EC</u>
<u>Given that:</u>
AE = EC
AE = 12 cm
Now,
AB = AE + EB
AB = 12 + 5
AB = 17 cm
<u>ABCD is a trapezoid / trapezium</u>
So,
Area of Trapezium =
Where AB = 17 , DC = 8 and EC = 12
Area of Trapezium =
Area of Trapezium = (25)(6)
Area of Trapezium = 150 cm²
