A rectangle has area 49 m2, Express the perimeter of the rectangle as a function of the length L of one of its sides. state the domain of p, Assurne the length of the rectangle is larger than its width. Enter your answer using interval notason Need Help? of fans are shown

Explanation / Answer

a) Let the length of rectangle be L. Let the breadth be B.

Area of rectangle = L x B

49 = LB => b = 49/L

Perimeter of rectangle = 2(L+B) = 2(L + (49/L)) = 2L + (98/L)

b) If length and breadth were equal, then length = breadth = L

Area = L x L => 49 = L^2 => L = 7

But Length is greater than breadth. Hence, length has to be greater than 7.

=> Domain of P : (7,infinity)
