Answer:
88 cm
Step-by-step explanation:
The composite figure is made by arranging four identical rectangles around the side of a square.
The area of the square is .
So the side length of the square is,
The area of each rectangle is of the area of the square.
So the area of each rectangle is,
As the breadth of each rectangle is equal to the side length of the square i.e 6 cm, so
Then perimeter of the cross pattern figure will be,
Answer to problem 1 is {-144,-192}
Answer to problem 2 is {-12,-12}
-------------------------------------------------
Explanation:
Vector u is given to be u = {-18,-24}
To compute the vector 8*u, we multiply both sides by 8 and multiply each coordinate by 8
The rule I'm using is if u = (a,b) then k*u = (k*a,k*b)
So,
u = {-18,-24}
8*u = 8*{-18,-24}
8*u = {8*(-18),8*(-24)}
8*u = {-144,-192}
Problem 2 is handled the same way
f = {-2,-2}
6*f = 6*{-2,-2}
6*f = {6*(-2),6*(-2)}
6*f = {-12,-12}
