Nick wants to pave the rectangular patio of his new house. The patio has length 5.25 metres and width 3 metres. He needs 81 bricks per square metre. How many bricks does Nick need for the whole patio?

1275.75 bricks

Step-by-step explanation:

First lets find the area of the rectangular patio:

(area of a rectangle=l*w)

5.25*3=15.75

there are 15.75 square meters in the patio

if there is 81 bricks per sq meter how many bricks are there for 15.75 square meters?

for the answer we have to multiply 81 with 15.75

so

81*15.5=1275.75
