Question:

• Written above

Given:

• The perimeter of room is 18m and width 4m

To Find:

• Length and area of room

______________________

$\huge\underline\orange{αnswer:-}$

______________________

⟶ Perimeter of room = 2*(Length + breadth)

⟶ 18m = 2*( Length + 4m)

⟶ $\frac{18}{2}$ = Length + 4m

⟶ 9m = Length + 4m

⟶ 9m - 4m = Length

⟶ 5m = Length

Hence Length = 5m

______________________

⟶ Area of room = Length * Breadth

⟶ Area of room = 5m * 4m

⟶ Area of room = 20m

Hence area is 20m

______________________

We got length $\sf\green{5m}$ and area $\sf\red{20m}$
