Answer:
1. height: 18√2 ≈ 25.46 inches; length: 36√2 ≈ 50.91 inches
2. length: 27 inches; width: 24 inches
Step-by-step explanation:
1. The area of a triangle is given by ...
A = 1/2bh
where b represents the base length, h represents the height.
Filling in the numbers, we get ...
648 in² = 1/2(2h)(h)
h = (√648) in = 18√2 in ≈ 25.46 in
The height is 18√2 inches, about 25.46 inches; the base is 36√2 inches, about 50.91 inches.

2. The area of a rectangle is given by ...
A = lw
where l represents the length, and w represents the width.
Filling in the numbers, we get ...
648 in² = (w+3)(w)
w² +3w -648 = 0 . . . . . . . rearrange to standard form
(w -24)(w +27) = 0 . . . . . . factor
The positive value of w that makes a factor zero is 24.
The length of the poster is 27 inches; the width is 24 inches.
Answer:
Width = 5 cm
Length = 7 cm
Step-by-step explanation:
Width = w
Length = 2w - 3
Perimeter = 24 cm
2* (length + width ) = 24
2*(2w-3 +w) = 24
2*(3w -3) = 24
3w - 3 = 24/2
3w - 3 = 12
3w = 12+ 3
3w = 15
w = 15/3
w = 5cm
Length = 2w - 3 = 2*5 - 3 = 10-3 = 7 cm
length = 7 cm

Considering the function , all points in the format are in the graph.
<h3>What are the points on the graph of a function f(x)?</h3>
Considering a function defined by the rule y = f(x), all points in the format (x,f(x)) are in the graph.
In this problem, the function is:
.
Hence all points in the format are in the graph.
