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 strips. If the strips have the same length to width ratio as the original, the ratio is A) √p:1 B)p:1 C) P: √5+1 D)p: 2​

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
