Question

parallel lines are drawn on a rectangular piece of paper the paper is then cut along each of the lines forming p identical rectangular stips if the strips have the same length to the width ratio as the original ,the ratio is

Answer 1

Step-by-step explanation:

The length of Rectangle is 30cm

The breadth of rectangles 3cm

The perimeter of rectangles is

2(l+b)

2×33=66cm

For Two rectangles 2×66=132cm

The Cross section leads to decrease in Perimeter by 3×4=12cm

So the perimeter of cross section is 132−12=120cm
