Question

A rectangular sheet of paper is 5⅔ cm long and 3⅕ wide find its perimeter step by step​

Answer 1

Answer:

Given:-

• Length = $5\dfrac{2}{3}$

• Breadth = $3\dfrac{1}{5}$

To Find:-

• Its perimeter.

Solution:-

Length of rectangular sheet

= $5 \dfrac{2}{3} cm\:=\dfrac{17}{3} cm$

Width of rectangular sheet

= $3 \dfrac{1}{5} cm\:=\dfrac{16}{5} cm$

Perimeter of rectangular sheet

= 2( l + b )

Perimeter of rectangular sheet

= $2(\dfrac{17}{3}+\dfrac{16}{5})$

Hence, the perimeter of sheet is

$\dfrac{266}{15}cm.$

Answer 2

Answer:

Let the natural number be x² and its square

root be x.

Then, we have

x² + x = 132

x² + x - 132 = 0

x² + 12x - 11x -132 = 0

x (x + 12) - 11 (x +12) = 0

(x+12) (x - 11) = 0

x = -12
