Answer 1

Your answer is 60 cm.

Explanation:

Area of triangle = ½ b × h

330 = ½ b × 11

330 × 2/11 = b

30 × 2 = b

∴ b = 60 cm

Answer 2

To find : base of triangle .

Given : area of triangle = $330\ cm^{2}$ , height = $11\ cm$

Solution :

• We know that , area of triangle is given by $\frac{1}{2}$ multiplication of base  and height .

         $Area\ of\ triangle = \frac{1}{2} \times base \times height$

                         $330 cm^{2} = \frac{1}{2}\times base \times 11\ cm \\\frac{330cm^{2}\times 2 }{11cm} = base \\base = 60 \ cm$  

Hence , base of triangle is $60 \ cm$ .
