Answer 1

Answer:

88.2cm

Step-by-step explanation:

area= 50×30=1500 sq. cm.

tape breadth=17m

length of the tape used =1500÷17=88.2cm

Ans=88.2 cm

Answer 2

Step-by-step explanation:

The length of the tape is 63 cm.

Step-by-step explanation:

Given : The top of a rectangular box of sides 50cm by 30cm is covered with a tape of breadth 17 cm.

To find : What is the length of tape used?

Solution :

Since the Perimeter and length of the tape will be same,

Let the length be x

P=2(l\times b)P=2(l×b)

2(50+30)=2(x+17)2(50+30)=2(x+17)

100+60=2x+34100+60=2x+34

160=2x+34160=2x+34

160-34=2x160−34=2x

126=2x126=2x

x=\frac{126}{2}x=

2

126

x=63 cmx=63cm

Therefore, The length of the tape is 63 cm.
