Question

Find the area of each of the following triangles.​

Answer 1

Answer:

Area of the given triangles are $6.4\ cm^2, \ 6 \ cm^2, \ 1\ cm^2$ and $36\ cm^2$

Step-by-step explanation:

The formula to find the area of a triangle with base $b$ and height $h$ is,

$Area = \dfrac{1}{2}bh$

(i) The height is 3.2 cm and the base is 4 cm. Thus the area of the triangle is,

$\dfrac{1}{2}bh= \dfrac{1}{2}\times 3.2 \times 4= 6.4\ cm^2$

(ii) The height and the base of the triangle are 3 cm and 4 cm respectively. So the area is,

$Area= \dfrac{1}{2}\times 4\times 3=6 \ cm^2$

(iii) The height is 1 cm and the base is 2 cm. Hence the area of the triangle is,

$\dfrac{1}{2}\times 1 \times 2= 1\ cm^2$

(iv) The height and the base of the triangle are 6 cm and 12 cm respectively. So the area is,

$Area= \dfrac{1}{2}\times 12\times 6=36 \ cm^2$
