Answer 1

${\huge{\boxed{\tt{\color {lime}{✿Answer:-}}}}}$

• Area of the wall = 216m².
• Perimeter of the wall = 60m.

${\boxed{\tt{\color {orange}{✿\: Step-\: By-\: Step\: \:Explaination:-\:}}}}$

$\huge \underline \mathfrak\pink{Given:- }$

• Length of the wall = 18m.
• Breadth of the wall = 12m.

$\huge \underline \mathfrak\pink{To~Find:- }$

• The Area of the wall.
• The Perimeter of the wall.

$\huge \underline \mathfrak\pink{Solution:- }$

Formula Used To Find The Area of the wall:-

${\boxed{\tt{\color {turquoise}{Area = (Length × Breadth)units.}}}}$

After Solving:-

${\tt{\color {turquoise}{∴ \: Area = (18 × 12) {m}^{2} }}} \\ {\tt{\color {turquoise}{→}}} \: {\tt{\boxed{\color {turquoise}{216 {m}^{2} }}}}$

Therefore, Area of the wall = 216m².

Formula Used To Find The Perimeter of the wall:-

${\boxed{\tt{\color {turquoise}{∴ Perimeter = 2(l+b)units.}}}}$

After Solving:-

${\tt{\color {turquoise}{Perimeter = 2(18 + 12)m}}} \\ {\tt{\color {turquoise}{ →2(18 + 12)m}}} \\ {\tt{\color {turquoise}{ →2 \times 30m}}} \\ {\tt{\color {turquoise}{ →}}} \: {\tt{\boxed{\color {turquoise}{ 60m}}}}$

Hence, Perimeter of the wall = 60m.

Answer 2

Area = 216m²

Perimeter = 60m

Step-by-step explanation:

GIVEN:

• Length of the wall = 18m

• Breadth of the wall = 12m

TO FIND:

• Area of the wall

• Perimeter of the wall

SOLUTION:

We know that a wall is in the shape of rectangle. So, to find the area of a rectangle, we use the formula:

➠ Area of rectangle = Length × Breadth

Apply the formula:

➠ Area of the wall = 18 × 12

➠ Area of the wall = 216m²

To find the perimeter of a rectangle, we use:

➠ Perimeter of rectangle = 2(Length+Breadth)

Apply the formula:

➠ Perimeter of the wall = 2(18+12)

➠ Perimeter of the wall = 2×30

➠ Perimeter of the wall = 60m

Hence, the Area and Perimeter of the wall are 216m² and 60m respectively.
