What is Area of rectangle?

Area of rectangle is the region occupied by a rectangle within its four sides or boundaries. The area of a rectangle depends on its sides.

Area of poster = l X w

w  ·  l  = 72

x  ·  x + 5 = 72

x . x = 72 - 5

x · x = 67

x² =  67

√x²  =  √67

Width x ≈ 8.185

so, by adding 5 inches, we get that

L = x + 5  = 8.185 + 5

length L = 13.185

Thus, the width of the poster is 8.185 inches and the length of the poster is 13.185 inches.
