Question

a rectangular garden is 100 metre long and 85 metre broad. An inside walking track 7 m wide is to buil. Find out the area of the walking track.​

Answer 1

Step-by-step explanation:

Given length of garden =100 m

breadth of garden =85 m

width of walking track =7 m

here, area of walking track =

total area of garden - area of garden not used for walking.

Now,

let's find area of garden =length * breadth

=100 * 85 = 8500 m^2

Now,

length of garden not used for walking = 100-7

= 93 m

breadth of garden not used for walking = 85-7 = 78m

So area of garden not used for walking = 93 * 78 = 7254 m

Therefore,

area of walking track= 8500 - 7254 = 1246m
