Question

area of a rectangle is 72 cm . perimeter is 11 times the length of rectangle. find the length​

Answer 1

area of rectangle=length*breadth

Step-by-step explanation:

given perimeter=11length

11l=2*(l+b)

11l=2l+2b

9l=2b

l*b=72

$\frac{9l^{2}}{2} =72\\l^{2} =\frac{72*2}{9} \\l^{2}=16\\l=4$

b=18

length of rectangle=4cm
