Question

Two rectangular pieces of paper strips, each of length 30 cm and width 3 cm, are pasted at right Angeles to make the shape of a cross. Find the perimeter of the cross

Answer 1

66cm is the perimeter

Answer 2

Answer:

120 cm

Step-by-step explanation:

Length of 1 strip = 30 cm

Width = 3 cm

Perimeter of 1 strip = 2(l+b)=2(30+3)=66

Perimeter of 2 strips = 66+66=132 cm

Since Two rectangular pieces of paper strips are pasted at right Angeles to make the shape of a cross.

So, perimeter of cross = 132 cm - 4(3)=120 cm

Hence the perimeter of cross is 120 cm
