Answer:
m
Step-by-step explanation:
Given parameters:
Length of rope = 11m
First length cut off = m
Second length cut off = m
Unknown:
Remaining length = ?
Solution:
Let us find the total length cut off first;
= m +
m
=
= m
So,
Remaining length = 11 -
=
= m
Answer:
The area of triangle for the given coordinates is 1.5
Step-by-step explanation:
Given coordinates of triangles as
A = (0,0)
B = (3,4)
C = (3,2)
So, The measure of length AB = a =
Or, a =
Or, a =
Or, a =
∴ a = 5 unit
Similarly
The measure of length BC = b =
Or, b =
Or, a =
Or, b =
∴ b = 2 unit
And
So, The measure of length CA = c =
Or, c =
Or, c =
Or, c =
∴ c = unit
Now, area of Triangle written as , from Heron's formula
A =
and s =
I.e s =
Or. s =
So, A =
Or, A =
Or, A = ×
∴ Area of triangle = 1.5
Hence The area of triangle for the given coordinates is 1.5 Answer
