You are ordering linoleum for an 18' by 15' kitchen, but when you get to the store the measurements are in square yards, how much should you order

The unit ' is used for the foot. Each yard is equal to 3 feet. We just have to convert the given dimensions in yards. 
       18':     (18') x (1 yard / 3 ft) = 6 yards
        15':    (15') x (1 yard / 3 ft) = 5 yards

The linoleum that you will order should have a dimension of 6 yd by 5 yd. 

Ithink the answer is b i hope it my friend message me if i’m wrong and i’ll change my answer and fix it for you
