Find all possible values for the length of the rectangle

Question

The width of a rectangle is 26 centimeters, Find all possible values for the length of the rectangle is the perimeter is at least 364 centimeters

Answer 1

P=2l+2w

2l+(2*26)>364

2l+52>364

2l>364-52

2l>312

l>312/2

l>156 cm

Answer 2

The perimeter formula is 2(L + W) = P    or P = 2L + 2W.

When w = 26 and P = 364 are substituted into the formula, it becomes

 

364 < 2L + 2*26

Simplify.

2L + 52 > 364

Subtract 52 from each side of the equal sign.

2L > 312

Divide by 2.

L > 156Your answer needs to be that the length needs to be greater than or equal to 156 cm.
