Question

A lawn is 80m long and
60m wide. In the middle
of the lawn there are two paths 5m wide, Parallel
to the sides of the lawn. These
paths cut each other at right angles. Find:
(i) The area of the paths.
(ii) The area of the remaning portion of the lawn.​

Answer 1

Answer:

Step-by-step explanation:

Through the centre of the lawn, two paths of 2 m width intersect each other at right angles

 

That means those paths will be in the form of two rectangles,

the first one of 80 x 2

and the other will be of 28 (30-2) x 2 ... (Because these two paths intersect each other internally)

 

Area of path 1 = 80 x 2 = 160 m2

Area of path 2 = 28 x 2 = 56 m2

Answer 2

Answer:

i 675mcube

ii 4125mcube

Step-by-step explanation:

Area of path 80x5+60x5-5x5=675m3

Area of remaining portion=total area-area of path

=80x60-675=4125m3
