Question

Another tent has the perimeter of 7.2 metres. If the width is 1.3 metres, what is the length?

Answer 1

P = 2( L + W)
P = 7.2
W = 1.3

7.2 = 2(1.3 + L)
7.2 = 2.6 + 2L
7.2 - 2.6 = 2L
4.6 = 2L
4.6/2 = L
2.3 = L <== length is 2.3 m 

Answer 2

Answer:  Length of tent would be 2.3 meters.

Step-by-step explanation:

Since we have given that

Perimeter of tent = 7.2 meters

Width of tent = 1.3 meters

Since we have given that

Perimeter = 2( length + width)

$7.2=2(Length+1.3)\\\\\dfrac{7.2}{2}=Length+1.3\\\\3.6=Length+1.3\\\\3.6-1.3=Length\\\\2.3\ m=Length$

Hence, Length of tent would be 2.3 meters.
