Answer 1

Answer:

64

Step-by-step explanation:

p=2(l+b)

p=2(12+20)

p=64

Answer 2

Answer:

56 cm^2

Step-by-step explanation:

Given: side of rectangle is 12 cm and diagonal is 20 cm.

we will calculate the other side of rectangle by using Pythagoras theorem:

By applying Pythagoras theorem we will get 16 cm.

Formula for perimeter of rectangle: 2(l+b)

2 ( 16 + 12 )

2 (28)

56 cm ^ 2

Hence answer is 56 cm ^2
