Answer:
Area = 16 units²
Step-by-step explanation:
<u>Points to remember</u>
<u>Distance formula</u>
The distance between two points (x1, y1) and (x2, y2) is given by
Distance = √[(x2 - x1)² + (y2 - y1)²]
<u>To find the length and breadth of rectangle</u>
Let the points be (1, 7) , (5, 3)
Distance = √[(x2 - x1)² + (y2 - y1)²]
= √[(5 - 1)² + (3 - 7)²]
= √[(4)² + (-4)²]
= √32 = 4√2
If the points be (5, 3) , (3, 1)
Distance = √[(x2 - x1)² + (y2 - y1)²]
= √[(3 - 5)² + (1 - 3)²]
= √[(-2)² + (-2)²]
= √8 = 2√2
Length = 4√2 and breadth = 2√2
<u>To find the area of rectangle</u>
Area = Length * Breadth
= 4√2 * 2√2
= 16 units²
Answer: If all three sides have the same length then it is an equilateral triangle, if only two sides have the same length then it is an isosceles triangle and if there are no sides that have the same length then it is a scalene triangle.
