Question

the perimeter of rectangle is 13cm and its width is 1.5cm find its length​

Answer 1

Given :

• Perimeter of Rectangle is 13cm.
• Width / Breadth is 1.5cm.

To Find :

• Length of Rectangle.

Solution :

$\longmapsto\tt{Width=1.5cm}$

Using Formula :

$\longmapsto\tt\boxed{Perimeter\:of\:Rectangle=2(l+b)}$

Putting Values :

$\longmapsto\tt{13=2(l+1.5)}$

$\longmapsto\tt{\cancel\dfrac{13}{2}=l+1.5}$

$\longmapsto\tt{6.5=l+1.5}$

$\longmapsto\tt{6.5-1.5=l}$

$\longmapsto\tt\bf{l=5}$

So , Length of Rectangle is 5 cm..

_______________________

• Perimeter of Rectangle = 2(l+b)
• Area of Rectangle = length × breadth
• Diagonal of Rectangle = √(l)² + (b)²
• Area of Square = (Side)²
• Perimeter of Sqaure = 4 × Side

Answer 2

Answer:

✡ Question ✡

➡ The perimeter of rectangle is 13cm and its width is 1.5cm. Find its length.

✡ Given ✡

➡ The perimeter of rectangle is 13cm.

➡ And the width is 1.5cm.

✡ To Find ✡

➡ Length = ?

✡ Formula Used ✡

⭐ $\text{\large\underline{\pink{Perimeter of Rectangle =2(l+b)}}}$

✡ Solution ✡

➡ Perimeter of rectangle = 13cm

➡ Breadth = 1.5 cm

⬛ According to the question,

=> 13 = 2(l+1.5)

=> $\dfrac{13}{2}$ = l+1.5

=> 6.5 = l+1.5

=> 6.5−1.5 = l

=> 5 = l

=> l = $\bold{\large{\fbox{\color{blue} {5}}}}$

∴ Length of Rectangle is 5 cm.
