The perimeter of a rectangle is 68
topjm [15]

Answer:

Length = 19 Cm

Explanation:

Given:

Perimeter of a rectangle = 68 Cm

Assume:

Width (B) = a

Length (L) = a + 4

Find:

Length of rectangle = ?

Computation:

Perimeter of a rectangle = 2(L+B)

⇒ 68 = 2(a + a + 4)

⇒ 68 = 2(2a + 4)

⇒ 68 = 4a + 8

⇒ 68 - 8 = 4a

⇒ 60 = 4a

⇒ a = 15 Cm

So, Width (B) =  15 Cm

⇒ Length =  Width (B) + 4

⇒ Length = 15 + 4

Length = 19 Cm
