15/4 cm
16/4 cm
17/4 cm
18/4 cm​

Answer 1

Step-by-step explanation:

Let 'l' and 'b' the length and width of the rectangle respectively.

Given, b=243cm

=411cm

and perimeter of the rectangle = 13 cm

2(l+b)=13

⇒2l+2b=13

⇒2l+2(411)=13

⇒2l+211=13

⇒2l=13−211

⇒2l=226−11

⇒l=415cm

∴ length of the rectangle = 415cm
