Step-by-step explanation:
By definition, the area of a rectangle is given by:
Where
l: length of the rectangle
w: width of the rectangle
Therefore, substituting values we have:
Rewriting the expression we have:
Answer:
The area of the rectangle as monomial is given by:
The surface area of the box is 252in.2 so I guess you should go with 324
I think we must use two numbers which have two digits and one of them must be one digited number.If we try it we can say our numbers are xy,ab and c.
xy + ab + c = 50
10x+y+10a+b+c = 50
10(x+a) + y+b+c = 50
Think about y+b+c. Maximum it can be 5+4+3 = 12 but it can't because there is a number which is multiple of 10.So it can be 10 maximum and x+a must be 4.
We can only use 1+3. 40 + y+b+c = 50 , y+b+c = 10. And other numbers are 2+4+5 = 11. 10 doesn't equal to 11 and it says there isn't any solution for this problem :)
