Question

please can any body tell the ans of all questions.​

Answer 1

★ Required Answers ★

☆ Area of square = 1/2 (diagonal)²or 2(side)²

☆ Area of an equilateral Triangle is √3/4a²

☆ Area of rhombus = b × h

☆' S ' indicates semi perimeter in heron's formula.

☆ Area of right angle triangle is = ½ × (Base × Perpendicular)

☆ Area of trapezium = h(a+b)/2

☆Area of triangle using heron's formula = √s{s(s-a)(s-b)(s-c)}

Additional information :-

Area of rhombus :-

➹Using Diagonals A = ½ × d1 × d2

➹Using Base and Height A = b × h

➹Using Trigonometry A = b² × Sin

★ Define " s " in the heron's formula?

➹ The s in Heron's formula denotes the semi-perimeter of a triangle, whose area has to $be$ evaluated.

Answer 2

Required Answer

Area of square = 1/2 (diagonal)²or 2(side)²

Area of an equilateral Triangle is √3/4a²

Area of rhombus = b × h

' S ' indicates semi perimeter in heron's formula.

Area of right angle triangle is = ½ × (Base × Perpendicular)

Area of trapezium = h(a+b)/2

Area of triangle using heron's formula = √s{s(s-a)(s-b)(s-c)}

Additional information :-

Area of rhombus :-

• Using Diagonals A = ½ × d1 × d2
• Using Base and Height A = b × h
• Using Trigonometry A = b² × Sin

Define " s " in the heron's formula?

The s in Heron's formula denotes the semi-perimeter of a triangle, whose area has to bebe evaluated.
