please answer me fast​

Answer 1

Step-by-step explanation:

1.Convert 8m into cm

=800cm

6m =600cm

area =2(800+600)=2×1400

=2800cm²

=2800÷25

=112 tiles is the correct answer.

2.perimeter =8×side

8×s=48

s=48÷8=6cm.

so,the length of its side is 6cm.

Answer 2

Answer:

1.

Length of the corridor= 8m

Breadth of the corridor=6m

Area of the corridor= l×b

= 8m×6m

= 48m² = 4800cm²

Side of the square tile= 25cm

Area of the square tile= (Side)²

= (25cm)² =625cm²

• No. of tiles required to cover the corridor =

Area of corridor

——————————

Area of square tile

= 4800cm²

———————

625cm²

=7.68 = 8 tiles approx.

Step-by-step explanation:

2. The perimeter of the regular octagon = 48cm

• 48cm = 8×side

= Side = 48cm

————

8cm

Side = 8cm
