Question

the area of the rectangular tile is : 2800sq.,3000sq.,3200sq.,3500sq.​

Answer 1

Answer:

In one part of the triangle, we have a=26cm,b=17cm and c=25cm.

Semi-perimeter of the triangle, s=

2

a+b+c

=

2

26cm+17cm+25cm

=34cm

Area of the triangle =

34×(34−26×(34−17)×(34−25)

cm

2

=

34×8×17×9

=204cm

2

So, area of the design =8× area of one triangle

=8×204cm

2

=1632cm

2

Now, area of the rectangular tile =50cm×70cm=3500cm

2

So, remaining area of tile = Area of the rectangular tile − Area of the design

=3500cm

2

−1632cm

2

=3500cm
