Question

A rectangular ground has a perimeter of 3.8 km. If the breadth of the ground is 900 m, find the length of the ground. pls answer

Answer 1

Answer:

length of the ground =

1000 m or 1 km

Step-by-step explanation:

given -

perimeter of ground = 3.8 km or 3800 m

breadth of ground = 900 m

to find -

length of ground

solution -

We know that rectangle's perimeter = 2(l+b)

ground's perimeter = 3800 m

2(l+b) = 3800 m

l+b = 3800÷2 m

l+900 = 1900 m

l = 1900-900 m

l = 1000 m

hope it helps.
