Question

the perimeter of a rectangular field is 80 m. if its breadth is 18 metre, find its length

Answer 1

Answer:

Step-by-step explanation:

Given,

Perimeter of rectangle =80m

Breadth =18m

Perimeter of rectangle =2(l+b)

80=2(l+18)

80/2=l+18

40=l+18

40-18=l

So, l=22m.

Hence, Length of the rectangle =22m.

Answer 2

Answer:

Perimeter = 2 ( l+ b)

80 = 2 ( l + 18 )

80/2 = l +18

40 = l + 18

40 - 18 = l

22 m = Lenght
