Question

8. The perimeter of a rectangular plot is 70 m. If the length of the plot is 20 m, find the area of the plot. ​

Answer 1

Answer: PERIMETER OF RECTANGLE = 2 ( LENGTH + BREADTH )

PERIMETER OF RECTANGULAR PLOT IS 70..

& IT'S BREADTH IS 15

PERIMETER OF RECTANGULAR PLOT = 2 ( L × B )

70 = 2 ( L + 15 )

70 = 2L + 30

70 - 30 = 2L

40 = 2L

L = 20

AREA OF RECTANGLE = LENGTH × BREADTH

AREA OF RECTANGLE = 20 × 15

= 300

Step-by-step explanation:

Answer 2

Step-by-step explanation:

The perimeter of rectangle=2(Length+breath)

Let beArea of plot be x =x(70+20)

=70x+20x

=90x
