Question

What is the perimeter of these 2 figures please help

Answer 1

First one = 13+14+15+10+10 = 62 cm

Second figure:-
length of the semicircle = 1/2 * pi * 12 = 18.85 cm

Perimeter = 6+8+10+18.85 = 42.85 cm

Answer 2

1) 62cm

2) 42.85cm

for the first one, you just need to add the numbers.
for the second one, you add 6,10, and 8. Then you find the circumference of the circle by using the diameter. After that, you divide the circumference by 2. Finally, add it to the other numbers!
