Question

Solve x : (a + b)2 x2 + 8 (a2 + a2) x + 16 (a - b) = 0 ​

Answer 1

Answer:

Given:

Ratio of the length to its width is 5:2

Width of the ground is 50 m.

To find:

Length of the ground?

Solution:

☯ Let's consider, Length of the school ground be 5x.

And, Width of the school ground be 2x.

\begin{gathered}\\\end{gathered}

⠀⠀⠀⠀\begin{gathered}\underline{\bigstar\:\boldsymbol{According\:to\:the\:question\::}}\\ \\\end{gathered}

★Accordingtothequestion:

Width of the ground is 50 m.

\begin{gathered}:\implies\sf 50 = 2x \\\\\\:\implies\sf x = \dfrac{\cancel{50}}{\cancel{\: 2}} \\\\\\:\implies\boxed{\frak{\pink{x = 25}}}\end{gathered}

:⟹50=2x

:⟹x=

2

50

:⟹

x=25

Now, Length of the ground = 5x.

\begin{gathered}:\implies\sf 5 \times 25 \\\\\\:\implies\boxed{\frak{\pink{125 \ m}}}\end{gathered}

:⟹5×25

:⟹

125 m

∴ Hence, length of the school ground is 125 m.
