Question

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

Answer 1

Step-by-step explanation:

perimeter of rectangle = 2(L+B)

70= 2(20+B)

70=40+2B

70-40=2B

30/2=B

15=B

area of rectangle =L*B

= 20*15

$= 300 {cm}^{2}$

Hope it helpful for you

Answer 2

${\mathcal{♡ANSWER♡}}$

perimeter of rectangle=2×(length+breadth)

=70=2×(20+a)

=70/2=20+a

=35=20+a

=35-20=a

=15=a.

area of rectangle=length×breadth

=20×15

=300.
