Answer 1

Answer:

5. 112 cm

6. 7200 cm²

Step-by-step explanation:

5. Given,

length of a rectangular strip = 53 cm

breadth = 5 cm

perimeter = 2(l + b )

= 2( 53 + 5)

= 2 × 56

= 112 cm

6. Given for a rectangular movie screen ,

length = 80 cm

breadth = 90 cm

area = lb

= 80 × 90

= 7200 cm²

Answer 2

Perimeter=2(l+b)

long=53 cm

wide/breadth=5cm

perimeter=2(l+b)
