Question

The height and the base of a triangular surface are 4m and 10m respectively. Calculate its area.

Answer 1

Given:-

• Base of triangular surface = 10m
• Height of triangular surface = 4m

To find:-

• The area of triangle

Solution:-

BaSe = 10m and height = 4m

Area of triangle =

$\frac{1}{2} \times base \times height \\ \\ = \frac{1}{2} \times 10 \times 4 \\ \\ = 5 \times 4 \\ \\ 20m$

Therefore,the area of triangle = 20m

Answer 2

Given-

• Hieght of triangular surface=4 cm
• Base of triangular surface=10 cm

To Find-

• Area of triangular surface

Formula to be use-

• Area of traingle= $\frac{1}{2} \times base \times hieght$

Step-by-step solution-

Area =

→ $\frac{1}{2} \times base \times hieght$

→$\frac{1}{2} \times 10 \times 4$

→$\frac{1}{2} \times 40$

→$20 \: sq \: cm$

hence, area of the triangular surface is 20 cm²
