Question

the length of a rectangle is twice its breadth,if the perimeter is 84 meters,find the length and breadth of the rectangle.​

Answer 1

ℚuestion:-

• The length of a rectangle is twice its breadth,if the perimeter is 84 meters,find the length and breadth of the rectangle.

Sólution:-

• Let the breadth of rectangular field be x.
• Then its length will be 2x.

➤Given perimeter=84m

Now:-

• Perimeter of a rectangle is given by:

➵2(l+b)

Therefore:-

$⇥2(l + b) = 84m$

$⇥2(2x + x) = 84$

$⇥2 \times 3x = 84$

$⇥6x = 84$

$⇥x = \frac{84}{6}$

$⇥x = 14$

• Length will be 28cm.
• Breadth will be 14cm
