Question

Find the length of a room whose area is 96sq.m and breadth is 6m. ​

Answer 1

Answer:

Given breadth of a rectangular room = 6m

Given perimeter of the rectangular room = 96m²

Length of the rectangular room = ?

We already know that perimeter of a rectangle is 2(l + b). So, we can find the length of the rectangular room by substituting the values.

⇒ Perimeter = 2(l + b)

⇒ 96m² = 2(l + 6)

⇒ 96m²/ 2 = l + 6

⇒ 48m = l + 6

⇒ 48m - 6 = l

⇒ 42m = l

∴ Length of the rectangular room is 42m

Thnx and have a nice day!
