Answer:
130cm
Step-by-step explanation:
A rectangle has 2 long sides and 2 short sides. To find the preimeter you add the length of all the sides together.
The long sides for this rectangle are 40cm each. And the short sides are 25cm each. So you have 2 sides that are 40cm and 2 sides that are 25 cm. The perimeter is therefore:
40 + 40 + 25 + 25 = 130cm
