What is the area of the rectangle? A. 60 units
B. 66 units
C. 70 units
D. 74 units

9514 1404 393

  D.  74 units²

Step-by-step explanation:

You can use the Pythagorean theorem to find the lengths of the sides. The short sides are each the hypotenuse of a 1 × 6 triangle, so their length is ...

  √(1² +6²) = √37

The long sides are each the hypotenuse of a 2×12 triangle, so their length is ...

  √(2² +12²) = 2√37

The area of the rectangle is the product of its length and width:

  (2√37)(√37) = 2·37 = 74 . . . . square units

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
