Answer:
The dimensions of the screen are
Length:102 feet
Width: 82 feet
Step-by-step explanation:
we know that
The area of the rectangle (movie screen) is equal to
where
L is the length
W is the width
we have
so
----> equation A
The screen is 20 feet longer than it is wide.
so
---> equation B
substitute equation B in equation A
solve for W
solve the quadratic equation by graphing
the solution is W=82 ft
see the attached figure
Find the value of L
therefore
The dimensions of the screen are
Length:102 feet
Width: 82 feet
Answer:
Area=32 square inches
Step-by-step explanation:
<em>Step 1: Determine the dimensions of the rectangle</em>
Width=w
Length=2×w=2 w
<em>Step 2: Determine the perimeter of the rectangle</em>
P=2(L+W)
where;
P=perimeter
L=length
W=width
In our case;
P=24 inches
W=w
L=2 w
replacing;
2(w+2 w)=24
2(3 w)=24
6 w=24
w=24/6=4
The width of the rectangle=4 inches
The length of the rectangle=2×4=8 inches
<em>Step 3: Determine the Area of the rectangle</em>
Area=length×width
where;
length=8 inches
width=4 inches
Area=8×4=32 square inches
Answer:
8
Step-by-step explanation:
5 x 6 = 30
6 x 6 = 36
8 x 6 = 48
Your answer would be the third and fourth one.
In the third one, you flip the shape over the X axis, and then flip it over X=5.
In the fourth one, you rotate it 180 degrees, around the point (5, 0).
Both would give you DBE.
