But first make me brainlyest.

Answer 2

Step-by-step explanation:

area = length * breadth

a = l * b

440 = l * 20

l = 440/20

l = 22

perimeter = 2 (l+b)

2 (22+20)

2 * 42

84 cm

perimeter = 130 cm = 2 ( l+b)

130 = 2(l + 30)

130/2 = l+30

65. = l+30

l = 65 -30

l = 35 cm

using this formula area = l * b (for rectangle)

perimeter = 2(l+b)

area = side*side (for square)

perimeter = 4* side

find the other part
