A rope 40m long is used to form a rectangle. If the length of the rectangle formed is 4m longer than the width. Calculate the ar
ivanzaharov [21]

Answer:

96 sq. m

Step-by-step explanation:

If the width is x, the length is x + 4 and since perimeter = 2 * (length + width), we can write:

40 = 2(x + x + 4)

40 = 2(2x + 4)

20 = 2x + 4

16 = 2x

x = 8 so x + 4 = 12, therefore the area is 8 * 12 = 96 square meters.

Find the unknown length of the right triangle. If necessary approximate the length to the nearest thousandth
WARRIOR [948]

We are given a right triangle and we are asked to determine the hypotenuse given the measure of its sides. To do that we will use the Pythagorean theorem:

h^2=(10km)^2+(20km)^2

Now, we solve the square:

h^2=100km^2+400km^2

Now, we add the values:

h^2=500km^2

Now, we take the square root to both sides:

h=\sqrt[]{500km^2}

Solving the operations:

h=22.361km

Therefore, the length of the hypotenuse is 22.361 kilometers.
