Answer 2

Answer :—

Given:

• The length of a rectangle is 2 cm more than its breadth.
• Its perimeter is 28 cm

Find:

• The length and breadth of the rectangle.

$\large{\underline{\mathfrak{Solution:-}}}$

Let the breadth of 1 cm = x

And length = x + 2

★ Formula for Perimeter of Rectangle :-

$\large{\boxed{\sf{Perimeter\;of\;Rectangle=2( Length+ Breadth)}}}$

» Putting values in formula:

${\sf{Perimeter\;of\;Rectangle=2( Length+ Breadth)}}$

= ${\sf{28\:cm=2(( x+2) + x )}}$

= ${\sf{28\:cm=2(2x + 2 )}}$

= ${\sf{28\:cm=4x + 4}}$

= ${\sf{28-4=4x}}$

= ${\sf{24=4x}}$

= ${\sf{\dfrac{24}{4}=x}}$

= ${\sf{6\;=x}}$

✝ The length and breadth are :-

Breadth - x = 6 cm

Length - x + 2 = 6 + 2 = 8 cm
