Question

the perimeter of the rectangle whose length is 25cm and breadth is 15cm ___________cm​

Answer 1

Answer:

$\color{black}\boxed{\colorbox{saffron}{Perimeter-2(length+breadth) }}$

$2(25 + 15) \\ \\ = 2 \times 40 \\ \\ = 80 \: cm$

Step-by-step explanation:

the perimeter of the rectangle whose length is 25cm and breadth is 15cm = 80cm

Answer 2

Given: Length and Breadth of the rectangle are 25 cm and 15 cm.

Need to find: Perimeter of the rectangle.

⠀⠀⠀⠀

⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀⠀⠀⠀⠀⠀

⠀⠀⠀⠀⠀⠀⠀

$\underline{\bf{\dag} \:\mathfrak{As\;we\;know\: that\: :}}$⠀⠀⠀⠀

⠀⠀⠀⠀

$\star\:\boxed{\sf{\pink{Perimeter_{\:(rectangle)} = 2(Length + Breadth)}}}$

⠀⠀⠀⠀⠀⠀

Therefore,

⠀⠀⠀⠀

$:\implies\sf Perimeter_{\:(rectangle)} = 2(25 + 15) \\\\\\:\implies\sf Perimeter_{\:(rectangle)} = 2 \times 40 \\\\\\:\implies{\underline{\boxed{\frak{\purple{Perimeter_{\:(rectangle)} = 80 \: cm}}}}}\;\bigstar$

⠀⠀⠀⠀

$\therefore{\underline{\sf{Hence,\; perimeter\;of\;the\; rectangle\;is\; \bf{80\;cm }.}}}$

• A Quadrilateral with four sides is called as rectangle. And, opposite sides of a rectangle are parallel and are equal in length.

• Perimeter of Rectangle = 2(Length + Breadth).

• Area of a Rectangle Formula, A = (Length × Breadth).

• Diagonal of a Rectangle Formula is, $\sf D = \sqrt{(l)^2 + (b)^2}$
