Let's assume that the given rectangle be ABCD and in that let ∆ABC be the right angled triangle formed from it.

Now we've been asked to find out the breadth. By applying Pythagoras theorem here in our rectangle ABCD we have,

  • length (l) = 30cm

  • diagonal (d) = 34cm

  • breadth (b) = ?

:\implies\tt{ {b}^{2}  =  {d}^{2}  -  {l}^{2} }

:\implies\tt{ {b}^{2}  =  {34}^{2}  -  {30}^{2} }

:\implies\tt{ {b}^{2}  = 1156 - 900}

:\implies\tt{ {b}^{2}  = 256}

:\implies\tt{b =  \sqrt{256} }

:\implies\tt{b = 16}

For the formula of area (a) = ? it is given by,

:\implies\tt{a = l \times b}

:\implies\tt{a = 30 \times 16}

:\implies\tt{a = 480 {cm}^{2} }

For the formula of perimeter (p) = ? is given by,

:\implies\tt{p = 2 \times (l + b)}

:\implies\tt{p = 2 \times (30 + 16)}

:\implies\tt{p = 2 \times 46}

:\implies\tt{p = 92cm}

  • The breadth, area and perimeter of rectangle is 16, 480cm² and 92cm.

Answer:

Step-by-step explanation:

To find the breadth use Pythagorean theorem

Breadth² = diagonal² - length²

               = 34² - 30²

               = 1156 - 900

               = 256

Breadth = √256 = 16 cm

Breadth = 16 cm

Perimeter = 2*(length + breadth) = 2*(30 + 16) = 2*46 = 92 cm

Area = length * breadth = 30 *16 = 480 cm²

NEED HELP ASAP<br>algebra 2​
Luden [163]

Answer:

x = sqrt(17)

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2 + b^2 = c^2

Let the unknown side be x

8^2 + x^2 = 9^2

64 + x^2 = 81

Subtract 64 from each side

x^2 = 81-64

x^2 =17

Taking the square root of each side

x = sqrt(17)
