Answer:

the cost is   £ 6,480

Step-by-step explanation:

given:

The perimeter of a square courtyard is 144 m

find:

the cost of cementing it at the rate of £5 per m².

<u>Perimeter = 4 Sides</u>

144 = 4 S

S = 144/4

S = 36

<u>Area = S²</u>

A = 36²

A = 1296 m²

cost of cementing the area =   1296 m² x £5 per m²  =  £ 6,480

therefore,

the cost is   £ 6,480
