Answer:
The perimeter of the drawing: 18 inches
The perimeter of the actual flower bed: 540 inches
If they were multiplied by 24 instead the actual perimeter of the flower bed would be 432 inches. The effect is that it decreases by 108 inches.
Step-by-step explanation:
Taking the 4 inches and 5 inches and multiplying them by 30 gets 120 by 150. If its a rectangle we will add together all 4 sides to get the perimeter of the actual one.

Answer:
4a^2 + 12ab + 9b^2.
Step-by-step explanation:
Use the identity (a + b)(a + b) = a^2 + 2ab + b^2 :
So
(2a + 3b)(2a + 3b)
= (2a)^2 + 2*(2a)(3b) + (3b)^2
= 4a^2 + 12ab + 9b^2.
