Question

Please help me understand how to do these problems. Many thanks in advance

Answer 1

The answer of the first problem is 107.3125 feet squared.

Problem 2: The answer is 4.5 miles an hour

Explanation:

The first question is simple. Area = base times height. Multiply the length and the width and it simply gives you the area which should be to the second power+the unit of measure.

The second is quick, but a bit more complex. You must covert all the fractions to an un-simplified fraction. Then you must divide the miles by the hours in fraction form, to get the answer of 4.5 mph

Answer 2

17= 12 5/16

18= 8 7/16

Explanation:

17- so what we are going to do is take 12 5/8 and 1 1/2 and multiply them like this: 12x 1 = 12; and 5/8 x 1/2 = 5/16

18- same as the question before, you are going to multiply the two numbers. this is what it'll look like: 8 x 1 = 8; and 1/2 x 7/8 = 7/16

i hope this helps :)
