Answer:
The new perimeter would be 36cm.
Step-by-step explanation:
The perimeter would change because you add 3 to two sides, because the perimeter originally was 5+5+10+10. Now, it's (5+3)+(5+3)+10+10. Which is 36.
Answer:
The perimeter changed by 6 cm.
Step-by-step explanation:
A rectangle has a width of 5 cm and a length of 10 cm.
The perimeter is = 2(length+width)
Perimeter = [tex]2(10+5)[/tex]
= [tex]2(15)[/tex]
= 30 cm
When the width is increased by 3, and lets assume that the length is same .
So, length is 10 cm and width is 8 cm.
Perimeter = [tex]2(10+8)[/tex]
= [tex]2(18)[/tex]
= 36 cm
Change in perimeter =[tex]36-30=6[/tex] cm
So, the perimeter changed by 6 cm.
