$\large\bf{\underline{Answer:}}$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $\large\bf{ = 3000 \:ft^2}$

__________________________________________

$\large\bf{\underline{Given:}}$

A 3 dimensional figure with 5 sides
it has 3 rectangles with dimensions 28 ft and 25 ft
And 2 triangles with base =30 ft and height = 20 ft

$\large\bf{\underline{To\: find:}}$

Total surface area of figure

$\large\bf{\underline{Therefore:}}$

$\bf{area \:of\: figure}$

‎ㅤ ${\bf = area \:of \:3\: rectangles + 2 \: triangles}$

$\large\bf{\underline{Formulas:}}$

$\boxed{\bf\pink{area\:of\: triangle= \frac{1}{2}\times base\times height}}$

$\boxed{\bf\pink{area\:of\: rectangle=length\times breadth}}$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $\large\bf{= 3\times (28 \times 25 )+ 2(\frac{1}{2} \times 30 \times 20)}$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $\large\bf{= 3 \times 800 + 2 \times 300}$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $\large\bf{=2400+ 600}$

‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎‎‎ ‎ ‎ $\large\bf{= 3000}$

Need help with Math.

KATRIN_1 [288]

Answer:

4^(11/20)

Step-by-step explanation:

The applicable rule of exponents is ...

(a^b)/(a^c) = a^(b-c)

Using that here, we have ...

4^(3/4)/4^(1/5) = 4^(3/4 -1/5)

= 4^(15/20 -4/20) = 4^(11/20)

What's the square footage of 24 by 17

WINSTONCH [101]

To do this question you need to multiply base times height. So it would be 24*17. After that, you should get 408 square feet.
