What is the formula of a rectangle?

Answer 1

This question is really confusing, as a rectangle is not a function. But we can calculate the area and perimeter of it, if that's what the question is about.

the formula for area is: length multiplied by width

A = lw

(Don't forget to add the units and ^2 at the end)

for perimeter, it's adding up all the sides: length + width + length + width. So,

l + w + l + w = 2l + 2w = 2(l + w)

P = 2(l + w)

(Same here, since you haven't been multiplying, you don't need ^2, but you still need the units in your final answer)
