Question

Which formula represents the perimeter of a rectangle?

A) a²
B) (1/3)b h
C) 2pi r
D) 2a+2b​

Answer 1

D

Explanation:

to have the perimetrr of a rectangle, since it has opposite sides equal "a" and "b" you multiply them by 2 and get the perimeter.

Answer 2

Answer: D

Explanation:

A rectangle's perimeter is the total side length, so addition is involved. It cannot be (a) because we established addition is involved, as well as (b) for not only that reason, but also because the 1/3rd value is unnecessary. (c) can be eliminated because since a rectangle isn't circular, no need to use a pi value. Therefore, the answer is D.

You can prove this by adding the side lengths of a rectangle, where the length and width have a line parallel to each other, and together they create the shape.
