Foundation level IV JEE Mock test 6 (Mathematics)

Area of a triangle is equal to:

• Base x Height

• 2(Base x Height)

• ½(Base x Height)

• ½ (Base + Height)

If the perimeter of an equilateral triangle is 180 cm. Then its side will be:

• 90cm

• 30cm

• 60cm

• 40cm

In Herons formula the term s means

• S= a + b +c

• S= (a + b + c)/2

• S= 2(a + b + c)

• None

According to Herons formula the area of triangle is

• A= √s(s+a)(s+b)(s+c)

• A= √(s-a)(s-b)(s-c)

• A= √s(s-a)(s-b)(s-c)

• None

The area of the equilateral triangle is

• A= √3/4side²

• A= √3/2side²

• A= √3/5side²

• None

The base of a right triangle is 8 cm and the hypotenuse is 10 cm. Its area will be

• 24 cm²

• 40 cm²

• 48 cm²

What in the area of an equilateral triangle with side 2 cm?

     

• √6cm²

• √3cm²

• √8cm²

• 4cm²

      Perimeter of triangle of different sides is

• P= a + b + c

• P= a + b

• P= b + c

• P= 2(a + b + c)

 The sides of a triangle are 3 cm, 5 cm and 6 cm. What is its area?

• 2√3cm²

• 4√14cm²

• 5√12cm²

• 2√5cm²

Herons formula is used to find
