Answer 2

Question :-

find the area of a triangle whose base is 1:2 m and height 1:9

Given :-

• base = 1:2m
• height = 1:9

To find :-

• area of the triangle

Formula :-

• area = 1/2 × breath × height

explanation :-

here it is given that height is 1:9 and base is 1:2 as we know that for finding area we need to use area = 1/2 × breath × height formula after putting values in the formula we get need to do division of 1/2 and breath and height after the division we need to multiply the breath and height so after multiplcation we will get our required answer.

Solution :-

$\rm :\longmapsto\: area = \frac{1}{2} \times b \: \times h \:$

$\rm :\longmapsto \: area = \frac{1}{2} \times 1.2 \times 1.9$

$\rm :\longmapsto\: area = \frac{1}{2} \times \cancel 1.2 \times 1.9$

$\rm :\longmapsto\: area = 1 \times 0.6 \times 1.9$

$\rm :\longmapsto\: area = 1.14$

∴ the area of the triangle is 1.14
