Question

find thelenth 5x+4 and breadth of the rectangle x-4 if its perimeter is 72 meters​

Answer 1

Answer:

length = 64

breadth= 8

hundred per cent .

Answer 2

Answer:

Length= (5x + 4)m

Breadth= (x - 4)m

∴2 (Length + Breadth) = Perimeter of the rectangle

⇒ 2{(5x + 4) + (x - 4)} = 72

⇒2{ 5x + x + 4 - 4 } = 72

⇒2 * 6x = 72

⇒12x = 72

⇒x = 72/12

∴ x = 6

So, Length = 5*6+4 = 34m and Breadth = 6 - 4 = 2m
