Question

The perimeter of a rectangle is 30 cm, and it's breadth is 6 cm, find its length and area.

Answer 1

Answer:

Here it is

Step-by-step explanation:

Given: Perimeter of the rectangle=30cm

Breadth of the rectangle=6cm

Therefore, Length of the rectangle =[Perimeter-2(Breadth)]/2

=[{30-2(6)}/2]cm

=[{30-12}/2]cm

=[18/2]cm

=9cm

Therefore, Area of the rectangle =Length×Breadth

=(9×6)cm^2

=54cm^2

Answer:

$\huge{\red{\boxed{\boxed{\green{\sf{LENGTH=9cm}}}}}}$

$\huge{\red{\boxed{\boxed{\green{\sf{AREA=54cm^{2}}}}}}}$

Step-by-step explanation:

$\huge{\red{\boxed{\boxed{\green{\underline{\red{\sf{SOLUTION-}}}}}}}}$

□Perimeter of rectangle= 30cm

□breadth= 6cm

To find:

○Length=?

○Area of rectangle=?

$let \: length \: be \: x \\perimeter \: of \: rectangle = 30cm \\ = )2(l + b) = 30 \\ = )2(x + 6) = 30 \\ = )x + 6 = \frac{30}{2} \\ = )x = 15 - 6 \\ = )x = 9cm \\ \\ area \: of \: rectangle = l \times b \\ = )9 \times 6 \\ = )54 {cm}^{2}$

$\huge{\red{\boxed{\boxed{\green{\sf{LENGTH=9cm}}}}}}$

$\huge{\red{\boxed{\boxed{\green{\sf{AREA=54cm^{2}}}}}}}$
