Question

The perimeter of a rectangle is 84 m. If it's breadth is 17 m find its length

Answer 1

p. of rectangle =2×(L+b)

84=2×(L+17)

84=34+2L

84-34=2L

50=2L

50/2=L

25=L

Answer 2

Answer:

perimeter of a rectangle 2*(l+b)

2(1+7)=84

(1+17)=84/2

(1+17)=42

L=42-17=25m

then length is 25 cm
