Answer»

☁️ |||_ANSWER_||| ☁️

:⇝ The side of the square is 30cm.

 ⠀ ━━━━━━━━━━━━━━━━━

STEP-BY-STEP EXPLANATION:

☁️ GIVEN:-

  • The area of the rectangle = The area of the square.
  • The length of the rectangle = 90cm.
  • The BREADTH of the rectangle = 10cm.

 ⠀ ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

☁️ To Find:-

  • The side of the square.

 ⠀ ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

☁️ Solution:-

First we NEED to find the area of the rectangle through the given length and breadth because here, area of the rectangle is equal to the area of the square.

And then, we can find the side of the square, after finding the area of the rectangle.

 ⠀ ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

☁️ So, Area of the rectangle:-

Formula Applied:-

⇝ Area of the rectangle = (l×b) SQ. units.

After Substituting The Values:-

⇝ (90×10)cm²

⇝ 900cm²

☁️ Now, The side of the square:-

Formula Applied:-

⇝ Side of the square = √(Area) units.

After Substituting The Values:-

⇝ √(900)cm

⇝30cm

 ⠀ ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

∴ Hence, The side of the square is 30cm. ✔
