Answer:
The least number of square stones of 210 cm * 210 cm that are required to pave the rectangular courtyard are 10.
Step-by-step explanation:
Restate the dimensions in cms.
Courtyard measures 1040 cm x 1512 cms
If this courtyard is to be paved using square stones, the dimension of stone should completely divide 1040 & 1512
1040 = 2 x 2 x 2 x 2 x 5 x 13 = 2⁴ x 5 x 13
1512 = 2 x 2 x 2 x 3 x 3 x 3 x 7 = 2³ x 3³ x 7
HCF(1040,1512) = 2³ = 8
Area of courtyard = 1040 x 1512 cm²
Area of each stone = 8 x 8 = 64 cm²
No of stones requured = 1040 x 1512/64
= 24570
