AB = BD = 10cm

Now using the Pythagorean theorem:

26^2 = 10^2 + BC^2

Simplify:

676 = 100 + BC^2

Subtract 100 from both sides:

576 = BC^2

Take the square root of both sides:

BC - sqrt(576)

BC = 24 cm

A rectangular flying carpet is 1 1/2 m wide and 2 m long what is the area of the carpet

d1i1m1o1n [39]

Hi there! :)

Answer:

The area of the carpet is 3m².

Step-by-step explanation:

First off, the formula to calculate the area of a rectangle is this: A = L × W

Where "A" is the area, "L" the length and "W" the width.

Now that you have that, replace all the information you know in the equation in order to find the value of "A", which is what we are looking for:

- Just keep in mind that 1 1/2 is the same thing as 1.5

- The term "wide" is used to give the "width"

- The term "long" is used to give the "length"

A = L × W

A = 2 × 1.5

A = 3

There you go! I really hope this helped, if there's anything just let me know! :)
