Please help me understand this math problem! :D

48 cm^2

Step-by-step explanation:

First find the area of each shape.

2 triangles- [bxh]x1/2

(4 times 3)(divided by 2) = 6, but there are 2 triangles so 6+6=12

Square- (l x w)

3 times 3 (You get the other three from the other side of the rectangle) =9

Left rectangle- (l x w)

3 times 4 = 12

Right rectangle- (l x w)

5 times 3 (You get the three from the side of the square) = 15

Total: 2 triangles Area + Square Area  + Left rectangle Area+ Right rectangle Area = Surface Area

12 + 9 + 12 + 15 = 48 cm^2

Hope this helps!!

Step-by-step explanation:

let the total charge be y

and the number of rose be x

Florist A charges

y=40+4.75x1

Florist B charges

y=25+5.2x2

to solve for the number of roses we need to equate 1 and 2

40+4.75x=25+5.2x

40-25=5.2x-4.75x

15=0.45x

x=15/0.45

x=33.33

The number of roses that will be less expensive to order from A is 33.33
