Question

Which measurement is the width of this rectangle? Area = 112 cm²

Answer 1

I think that there was probably a rectangle that you didn't include in the question
area of rectangle=legnth times width
area=112 cm^2
legnth>width
assuming that since your grade level doesn't normally do decimals, I will only assume whole number legnths and widths
try and factor and find the pairs that make up 112
112=2 times 2 times 2 times 2 times 7
the pairs are
1&112
2&56
4&28
7&16
8&14

notice that the smaller pairs are on the left side
they are 1,2,4,7,8
these are the possible legnths
look at the answer choices and see which one is in the list 2 lines abouve this line (1,2,4,7,8)
the only match is 8

therefor the answer is B. 8cm

Answer 2

To find the area of a rectangle, multiply the length by the width.
The formula is:, where  is the area,  is the length,  is the width, and · means multiply.
Because 112 = 14 · 8 , then, the width of the rectangle is 8 cm;
The answer is B.
