Question

In Fig. I length - 42 cm. breadth =
21 cm. From Fig. I a square of side 2 cm
is cut. Find the perimeter of the figures
and compare them
Fig. 1
Fig. 2​

Answer 1

Perimeter of rectangle=2(l+b)

2(42+21)=126

and perimeter of square = 4a

Answer 2

Answer:

perimeter of rectangle=2(L+B)

2(42+21)=126cm

perimeter of square= 4×side

4×2=8

perimeter of figure=perimeter of rectangle - perimeter of square

126-8=118cm
