Question

find the perimeter of rectangle

Answer 1

a,l=6.5
b=3.2

perimeter=2(l+b)
=2(6.5+3.2)
=2(9.7)
=2×9.7
=19.4 is the perimeter of the rectangle

Answer 2

Question :-

Find the perimeter of rectangle.

a) l = 6.5 m b = 3.2 m

b) l = 4.8 mm b = 3.4 mm

c) l = 720 cm b = 640 cm

Answer :

a) l = 6.5 m b = 3.2 m

=> Perimeter of Rectangle = 2 ( l + b )

=> 2 ( 6.5 m + 3.2 m )

=> 2 × 9.7 m

=> 19. 4

b) l = 4.8 mm b = 3.4 mm

=> Perimeter of Rectangle = 2 ( l + b )

=> 2 ( 4.8 mm + 3.4 mm )

=> 2 × 8.2 mm

=> 16.4 mm

c) l = 720 cm b = 640 cm

=> Perimeter of Rectangle = 2 ( l + b )

=> 2 ( 720 cm + 640 cm )

=> 2 × 1360 cm

=> 2720 cm
