Your school wants to take out an ad in the paper congratulating the basketball team on a successful season, as shown to the right. The area of the photo will be half the area of the entire ad. What is the value of x?
length=7
width=5
There is no photo to the right...
So... is the total area of the ad 7x5 = 35 units squared?
That would make half the area (that is for the picture)
35/2
Again... sorry this website wont allow pictures.
sorry i just copied and pasted. okay i will try it.
To find the value of x, we need to determine the area of the entire ad and then calculate half of that area.
The formula to find the area of a rectangle is: Area = length * width
Given:
Length of the rectangle = 7
Width of the rectangle = 5
Using the formula, we can calculate the area of the entire ad:
Area of the entire ad = 7 * 5 = 35 square units
We are told that the area of the photo will be half the area of the entire ad. Therefore, we need to calculate half of the area of the entire ad:
Half the area of the entire ad = 35 / 2 = 17.5 square units
Now, we need to find the dimensions of the photo. The area of a rectangle can be calculated using the formula: Area = length * width.
Let's assume the length and width of the photo are x. Therefore, the area of the photo can be represented as: Area of the Photo = x * x = x^2.
We know that the area of the photo is half the area of the entire ad, so we can write the equation: x^2 = 17.5.
To solve for x, we can take the square root of both sides of the equation: square root(x^2) = square root(17.5).
x = square root(17.5).
Using a calculator, we can find that the value of x is approximately 4.183.
