A mural on the school wall has an area of 4800 square inches. If the length of the mural is 1 1/13 times the width, what are the dimensions of the mural?
L = 14 w/13
(14 w/13)(w) = 4800
w^2 = 13 (4800/14)
w = 66.76
To find the dimensions of the mural, we need to set up a system of equations based on the given information.
Let's say the width of the mural is x inches.
According to the given information, the length of the mural is 1 1/13 times the width. We can express this as (14/13)x inches.
The area of a rectangle is given by the formula: Area = Length × Width.
So, we can set up the equation: (14/13)x × x = 4800.
To solve this equation, we can simplify and solve for x.
Multiplying the terms on the left side of the equation:
(14/13)x^2 = 4800.
To isolate x^2, we multiply both sides of the equation by (13/14):
x^2 = (4800 × 13/14).
Now, we can find the value of x by taking the square root of both sides of the equation:
x = √[(4800 × 13/14)].
Calculating this using a calculator or by hand will give you the width of the mural. Once you have the width, you can calculate the length by multiplying it by (14/13).
I'll leave the actual calculation to you.
