Question

Area of a triangle with base 7 cm and height of double the base is *

98 sq cm

49 sq cm

196 sq cm​

Answer 1

Answer:

♡49 sq cm

Step-by-step explanation:

☆To find:

• Area of the triangle

☆Given:

• Base = 7cm
• The height is double the base .
• Therefore, height =7×2=14

☆Formula:

• $area = \frac{1}{2} \times base \times height$

☆Solution:

• $\frac{1}{2} \times 7 \times 14 = 7 \times 7 = 49 {cm}^{?}$

☆Hence:

• Area of the triangle is 49 cm ²

☆Extra information:

• Area of scale scalene triangle(Heron's formula) = root over s(s-a)(s-b)(s-c).
• Area of triangle =1/2×base×height
• Pythagoras formula :
• Hypotenuse ²=Base ²+height ²
