The perimeter of a rectangular field is 240m.If it's length is 9pm, find:
(i) it's breadth
(ii) it's area



Step by step please

Solution:

Perimeter of the rectangle = 240m.

=> Perimeter of the rectangle = 2 x ( l + b ),

=> 240 = 2( 90 + b),

=> 120 = 90 + b,

=> b = 30.

=> The breadth of the rectangle = 30m.

Area of rectangle = (l × b)

=> Area of the rectangle = 90 x 30,

=> Area of the rectangle = 2700m².

Therefore, the breadth of the rectangle is 30m and the area of the rectangle is 2700 m².
