Question

the perimeter of a rectangle is 180m and its length is 10 metres more than its width find its length and width​

Answer 1

Answer:

length = 50

width = 40

Step-by-step explanation:

let the length be l

and width be b

2(l+b)=180

l=b+10

Answer 2

Answer:

length is 95 m and width is 85 m

Step-by-step explanation:

perimeter = 180m

let width be x

so length = x+ 10

     width = x

perimeter of rectangle = length + width

                                180= x+x+10

                                 180=2x+10

                                  180-10=2x

                                  170=2x

                                   x=170/2

                                   x=85

so width =85 m and 95 m
