Question

Please help me to solve these​

Answer 1

Answer:

The area of rectangular plot is 540 M square

it's length is 27 m

the formula of it's bredth is area /length

so, 540/27 = 20m

the formula of perimeter of a rectangle is 2(L+B)

the perimeter of rectangular plot is 2(27 + 20)

2*47 = 94

Answer 2

24 minutes

Answer:

Given:

Length = 180m

Breadth=120m

Distance she travel=Perimeter of rectangle ×5 [As shown above]

Perimeter of rectangle =2(l+b)

Therefore,

2(180m+120m)

=2×300m

=600m

Now,

Distance=600m×5

Therefore,

Distance=3000m

Now we have given with speed and distance

Since, Time=Distance/Speed

Time=3km/7.5km

Therefore,

Time=.4hr

Which is .4hr ×60min

=24min
