\bold{\huge{\pink{\underline{ Solution }}}}

\bold{\underline{ Given :-}}

  • <u>We </u><u>have </u><u>a </u><u>right </u><u>angled </u><u>triangle </u><u>whose </u><u>two </u><u>sides </u><u>that </u><u>is </u><u>perpendicular </u><u>and </u><u>hypotenuse </u><u>are </u><u>5</u><u> </u><u>units </u><u>and </u><u>1</u><u>2</u><u> </u><u>units </u>

\bold{\underline{ Let's\: Begin:-}}

<h3><u>According </u><u>to </u><u>the </u><u>Pythagoras </u><u>theorem</u><u>, </u></h3>

  • Pythagoras theorem states that the sum of squares of two small sides that is perpendicular height and base are equal to the square of longest side that is hypotenuse

<u>That </u><u>is</u><u>, </u>

\sf{\red{ ( Base)² + ( Perpendicular )² = ( Hypotenuse)²}}

\sf{ ( a )² + ( b )² = ( c )²}

<u>Subsitute </u><u>the </u><u>required </u><u>values</u><u>, </u>

\sf{ ( a )² + ( 5  )² = ( 13)²}

\sf{ a²  + 25 = 169}

\sf{ a² = 169 - 25 }

\sf{ a² = 144}

\sf{  a  = √144}

\sf{ a  = 12}

\sf{\blue{ Hence,\: Length \:of \:a\: is \:12 units }}

\sf {a}^{2}  =  {13}^{2}  -  {5}^{2}

Formula :

Base²= Hypotenuse² - Perpendicular ²

\\  \\

\hookrightarrow\sf {a}^{2}  =  {13}^{2}  -  {5}^{2}

\\  \\

\hookrightarrow\sf {a}^{2}  =169 - 25

\\  \\

\hookrightarrow\sf {a}^{2}  =144

\\  \\

\hookrightarrow\sf {a} = \sqrt{144}

\\  \\

\hookrightarrow\sf {a} = \sqrt{12 \times 12}

\\  \\

\hookrightarrow\sf {a} = 12

Remember the a² in formula has nothing to do with the a we have to find. :)

A new park was designed to contain two circular gardens. Garden A has a diameter of 50 m, and garden B has a diameter of 70 m. T
Nastasia [14]

Answer:

5,811.95\  m^2 of fabric.

Step-by-step explanation:

-The amount of fabric needed is equivalent to the  area of the two gardens.

-We calculate the combined areas as:

A=A_s+A_b\\\\=\pi r^2+\pi R^2\\\\=\pi(25^2+35^2)\\\\=1850\pi \ m^2\\\\=5811.95\ m^2

Hence, 5811.95 sq meters of fabric will be needed to cover the area of both gardens.
