Answer:
The distance between the two points (2 ,5) and (4, 8) is 3.61
Step-by-step explanation:
The distance between two points can be calculated by using formula
Here x₁ = 2, y₁ = 5, x₂ = 4 and y₂ = 8
Finding distance between two points
So, the distance between the two points (2 ,5) and (4, 8) is 3.61
Answer:
see explanation
Step-by-step explanation:
The perimeter is the sum of the 3 sides, that is
perimeter = 8 + 12 + 17 = 37 cm
To use Heron's formula for area (A)
A =
where a, b and c are the lengths of sides and s the semi perimeter
s = 37 ÷ 2 = 18.5
let a = 8, b = 12 and c = 17, then
A =
=
= ≈ 43.52 cm² ( to 2 dec. places )
