Answer:
BC is 10 unit
BD is 15 units
Step-by-step explanation:
Here, given the end points of the line segments, we want to calculate BD and DC
Mathematically, the distance between two points can be calculated using the formula;
D = √(x2-x1)^2 + (y2-y1)^2
For BD, we have the following
D = √(14-5)^2 + (14-2)^2
D = √(9)^2 + 12^2
D = √81 + 144
D = √(225)
Distance BD is 15 units
For BC, we have the following
D = √(11-5)^2 + (10-2)^2
D = √(6)^2 + 8^2
D = √100
D = 10
Answer:
c
Step-by-step explanation:
So length is 3.9 cm more than 3 times the width
perimeter is 32.6 cm
l = 3w + 3.9
P = l + l + w + w
32.6 = 3w + 3.9 + 3w+ 3.9 + w + w
combine like terms
32.6 = 7.8 + 8w
subtract 7.8 from both sides
24.8 = 8w
divide both sides by 8 to isolate w
3.1 = w
so we solved that the width is 3.1 cm
to find the length
l = 3.9 + (3*3.1)
l = 3.9 + 9.3
l = 13.2
The dimensions:
Length is 13.2 cm
Width is 3.1 cm
Hope this helps :)
