A composite figure is formed by combining a square and a triangle. Its total area is 52.5 ft. The area of the

otez555 [7]

The length of each side of the square is 3 ft.

<u>Step-by-step explanation:</u>

We have , A composite figure is formed by combining a square and a triangle. Its total area is 52.5 ft. The area of the triangle is 43.5 ft . We know that area of a square = $length^{2}$ . According to question:

area of square = $length^{2}$

area of triangle = 43.5 ft

total area = 52.5 ft.

Total area = area(square+triangle)

⇒ $43.5 + (Length)^{2} = 52.5$

⇒ $(Length)^{2} = 52.5- 43.5$

⇒ $(Length)^{2} = 9$

⇒ $(Length) = \sqrt{9}$

⇒ $Length= 3$

Therefore, the length of each side of the square is 3 ft.

Arithmetic Operations with Numbers Written Using Scientific Notation <br> (7 × 10^−9)(5 × 10^5)

taurus [48]

Answer:

After multiplication number will be $3.5\times 10^{-5}$

Step-by-step explanation:

We have given numbers which has to multiply using scientific notation

$7\times 10^{-9}\times 5\times 10^5$

We have to multiply the above number using scientific notation

We know that when two number are multiplied then there exponent power is being added

So when we multiply $7\times 10^{-9}\times 5\times 10^5$ there power will be added and after multiplication number will be $35\times 10^{-4}=3.5\times 10^{-5}$
