Question

The width of a rectangle is 20 units.Can the perimeter be 64 units when it’s length x is 11

Answer 1

The formula for perimeter is 2L +2W

Replace w with 20 and L with 11:

2(11) + 2(20) = 22 + 40 = 62

This does not equal 64, so the perimeter cannot be 64 with 20 and 11 being the dimensions.
