Answer» Given,Length of flower garden l = 5a mWidth of flower garden b = 3b m Then,Perimeter of flower garden= 2(l + b)= 2(5a + 3b) = 10a + 6b For a = 4, b = 1/2 aPerimeter = 10a + 6a/2= 10a + 3a= 13a= 134= 52 m

What is the perimeter of a flower garden whose length is 5a metres, andwidth is 3b metres when a -4 and ba?

Answer»

Given,Length of flower garden l = 5a mWidth of flower garden b = 3b m

Then,Perimeter of flower garden= 2(l + b)= 2(5a + 3b) = 10a + 6b

For a = 4, b = 1/2 aPerimeter = 10a + 6*a/2= 10a + 3a= 13a= 13*4= 52 m
