Answer 1

The length will be 4cm

Answer 2

Given thαt,

• The αreα of the rectαngulαr bαse of α pencil box is 28 sq. cm.
• The width is 7 cm.

☯️ We need to find the length of the bαse of rectαngulαr pencil box.

_________

To do so,

We must know thαt,

$\large{\boxed{\mathbf{\orange{ Area_{(Rectangle)} = length \times breadth}}}}$

Let's αssume thαt length be x.

:$\implies{\sf{x\:cm \times 7cm = 28cm^{2}}}$

• Take 7 to R.H.S.

:$\implies{\sf{x\:cm = \dfrac{28cm^{2}}{7cm}}}$

• Simplify this.

:$\implies{\sf{x\:cm = 4cm}}$

:$\large\implies{\sf{\boxed{\mathbf{\red{Length = 4cm}}}}}$

Hence, the length is 4cm.

And we αre done! :D
