Question

A path of width 2.21m is constructed all along outside a garden which is 5.5m long 5m wide find the area of path
class 7
perimeter and area
​

Answer 1

Step-by-step explanation:

Breadth of a rectangular courtyard =3.78m=378cm

Length of a rectangular courtyard =5.25m=525cm

Now, we have to find H.C.F os 378 and 525

378=2×3×3×3×7

525=5×5×3×7

Common factore=3×7

∴ H.C.F=21

Hence largest size of square tiles that can be paved exactly with square tiles is 21cm.
