7cm is
1) 2.52 m²
2) 0.1625 m?
3) 108cm
4) 25.2 cm?
And also say how to mark as brainliest u

Answer 1

Answer:

1/2*base *height=1/2*7.2*7=25.2cm²

therefore 4 is correct

Answer 2

Given :

⬤ Base of Triangle is 10 cm .

⬤ Height ot Triangle is 15 cm .

To Find :

⬤ Area of Triangle .

Formula Used :

$\sf[\:{Area \: of \: Triangle = \dfrac{1}{2} \times{b} \times{h}\:]}$

• b = base
• h = height

Solution :

• Base = 7.2 cm .
• Height = 7 cm .

According to the Formula :-

1/2 × b × h

1/2 × 7.2 × 7

1/2 × 72/10 × 7

36 × 7/10

252/10

25.2

Therefore , The Area of Triangle is 25.2 cm² .

Option d) 25.2 cm² is Correct .
