Question

find the area of a rectangle of side root8cm and root2cm​

Answer 1

Question:

Find the area of a rectangle of side √8cm and √2cm.

Analysis:

Rectangle: A Quadrilateral in which one Angle is 90° and two pairs of opposite sides are equal is called a Rectangle.

➝ Every Square is a Rectangle, But all Rectangles are not Squares.

✯ Area of Rectangle = Length × Breadth

✯ Perimeter of Rectangle = 2(l+b)

✯ Each diagonal has length ${\displaystyle d={\sqrt {\ell ^{2}+b^{2}}}}$

______________________

SoluTion:

Given,

Sides of Rectangle are

Length = √8cm & Breadth = √2cm

$\boxed{\sf{Area\;of\; Rectangle = Length×Breadth}}$

$→\;{\sf{\sqrt{8}×\sqrt{2}}}$

$→\;{\sf{\sqrt{8×2}}}$

$→\;{\sf{\sqrt{16}}}$

$→\;{\sf{\sqrt{4²}}}$

$→\;{\sf{4}}$

AnSweR:

Area of Rectangle ◕➜ $\Large\red{\bf{4cm²}}$
