Answer:
Step-by-step explanation:
Perimeter of square = 4×side
28 = 4×side
side = 28/4 = 7
Area of square = side × side = 7×7 = 49
Area of square = 1/2×(diagonal)²
49 = 1/2×(diagonal)²
Diagonal ² = 49×2 = 98
Diagonal = ✓98 = 9.8cm

Answer:
1) Perimeter of square = 4 × side
Given, perimeter = 28 cm
=> Side = 28 ÷ 4 cm = 7 cm
2) Area of rectangle = length × breadth
Given, area = 32 cm², length = 8 cm
=> Breadth = 32 ÷ 8 cm = 4 cm
