A=1/2(a+b)h ↔ A= [(a+b).h]/2
Cross multiplication:→2A = (a+b).h.
Divide both sides by (a+b):
2A/(a+b) =h
Answer:
a) 300
b) 900
Step-by-step explanation:
The length of the rectangle is 5 and the width is 3...
But since the rectangles are connected together, we could just work the problem like this:
5 x 2 = 10
_____________
3 x 5 = 15
15 x 2 = 30
The surface area of the shape is 10 x 30 = 300
______________________________________________
If the dimensions of the box were tripple, we would need to multiply the surface area by 3:
300 x 3 = 900
For the second question, the answer would be 900
Hope this helped you :-)
