Question

the area of a rectangular Courtyard 30 cm long is 450 m per square find its breadth and perimeter

Answer 1

I am assuming that " breadth " is width, and " 450 m per square " is 450 cm squared. ( if it were meters squared to area would be 4500000 cm squared )

Since Area is One length x Other Length, this means that Length is Area / other Length.

If one length is 30, that means that the other is 450 / 30, or 15

Width: 15

To find the perimeter, add 15 + 30 + 15 + 30 to get

Perimeter: 90
