Question

Find the length of a rectangle Whose perimeter is 92cm and width is 27cm
​

Answer 1

Let the length of the rectangle be l .

Perimeter of rectangle = 2 ( l + b )

92 = 2 ( l + 27 )

92 = 2l + 54

2l = 92 - 54

2l = 38

l = 38/2

l = 19

So , the length of the rectangle is 19 cm .

Answer 2

Answer:

perimeter =2(l+b)

2(l+27)=92

(l+27)=92/2

(l+27)=46

l=46_27

l=19cm
