Answer:length of the strip =3 1/3 meters
Step-by-step explanation:
Step 1
Given that
Area of the rectangular strip= 2/3 square meter
width = 1/5 meter
length = ?
W e know that the formulae for area of a rectangle = Length x width
using this equation, we will solve for length
Step 2
area of the rectangular strip= Length x width
Length = Area / Width
2/3 square meter / 1/5 meter
Length= 2/3 x 5/1 = 10/3= 3 1/3 meter
