the length of a room is 5.5 m and width is 3.75 m . what is the cost of paying the floor by slabs at the rate of $ 800 per sq . metre .
"c $ 16500 area = 5.5 × 3.75 sq . metre . cost for 1 sq . metre . = $ 800 hence , total cost = 5.5 × 3.75 × 800 = 5.5 × 3000 = $ 16500"
multiply(800, multiply(5.5, 3.75))
