Answer 2

Answer:

Perimeter of 1st object = 240 cm

Perimeter of 2nd object = 550 cm

Step-by-step explanation:

The first object is a rectangle

So, Perimeter = 2×(l+b) = 2 × (30 + 90)cm = 2 × 120 cm = 240 cm

The 2nd Object is also a rectangle

So, Perimeter = 2×(l+b) = 2 × (153 +122)cm = 2 × 275 cm = 550 cm
