Use the formula for the triangle A= 1/2bh For the rectangle A= lw Use the formulas and add the answer you got for both formulas. Remember b stands for base, h stands for height, l stands for length, and w stands for width. When the when the “letters” are next to each other, like bh, that means to multiply. The answer should be 2 _ _ ft squared Try to figure out what the other two missing numbers are! The answer begins with 2, good luck!
For this case we can make the following rule of three to solve the problem: 126 --------> 14 x -----------> 30 We clear the value of x: x = (30/14) * (126) x = 270 400 page books Answer: it could collate in 30 days about: x = 270 400 page books
