Question

the perimeter of the square is less than 28cm.What can be said about a)the length of one of its sides b)its area

Answer 1

Hi Mate Here is your Answer........

Perimeter of square = 4×side

Perimeter of square = 4×side28 = 4×side

Perimeter of square = 4×side28 = 4×sideside = 28/4 = 7

Perimeter of square = 4×side28 = 4×sideside = 28/4 = 7Area of square = side × side = 7×7 = 49

Perimeter of square = 4×side28 = 4×sideside = 28/4 = 7Area of square = side × side = 7×7 = 49Area of square = 1/2×(diagonal)²

Perimeter of square = 4×side28 = 4×sideside = 28/4 = 7Area of square = side × side = 7×7 = 49Area of square = 1/2×(diagonal)²49 = 1/2×(diagonal)²

Perimeter of square = 4×side28 = 4×sideside = 28/4 = 7Area of square = side × side = 7×7 = 49Area of square = 1/2×(diagonal)²49 = 1/2×(diagonal)²Diagonal ² = 49×2 = 98

Perimeter of square = 4×side28 = 4×sideside = 28/4 = 7Area of square = side × side = 7×7 = 49Area of square = 1/2×(diagonal)²49 = 1/2×(diagonal)²Diagonal ² = 49×2 = 98Diagonal = ✓98 = 9.8cm
