Considering the figure,
In ΔABC, right angled at B, we can use Pythagoras theorem :
..................(1)
Also we are given area of rectangle as 108 m²
Area of rectangle = length * breadth = x * y
.............(2)
........(3)
plugging the value of x from equation (3) in (1),
We can use quadratic formula to solve this.
On solving this we get four values of y as :
y=12, y=-12, y=9 and y=-9
since length cannot be negative we have two y values as :
y=12 and y=9
plugging these in equation (3) to get x as
x=108/y = 108/12 = 9
x = 108/9 =12
so we have two answers:
length =9 m and breadth = 12m
length =12 m and breadth =9m
Perimeter = 2(l+b)
Perimeter = 2(9+12) = 42m

Step-by-step explanation:
Question 1) Write an absolute value equation that is reflected, vertically shifted 2/3 units down and 1/2 units to the right.
Answer 1):
We know that absolute function is given by y=|x|
reflection happens when we multiply by negative sign so we get
y=-|x|
To get vertical shift down, we subtract so new equation is
y=-|x|-2/3
To get right shift by h unit, we replace x by (x-h) so the new equation is
y=-|x-1/2|-2/3
Hence final answer is
Question2) Write an absolute value equation with a horizontal shift 4 units to the right.
Answer:
We know that absolute function is given by y=|x|
To get horizontal right shift by h unit, we replace x by (x-h) so the new equation is
Hence final answer is .
Step-by-step explanation:
as we can see that the sides are in the ratio of 2:1 and are consecutive
so
a;b=2:1
a=4
b=8
