Question

plspls any one can solve this maths equation If you give correct answer I will give heart and brainlest and rating but if anyone gives wrong answer or spam I will report #nospam
pls give correct answer ​

Answer 1

Answer:

• Option (b) 79.2 cm² is the required area of ∆ ABC .

Step-by-step explanation:

According to the Question

It is given that,

• Base of Triangle ,b = 22cm
• Height of triangle ,h = 7.2 cm

we have to calculate the area of given triangle .

The area of triangle is calculated by

• Area of Triangle = 1/2 × base × height

by putting the value we get

→ Area of ∆ABC = 1/2 × 22 × 7.2

→ Area of ∆ABC = 11 × 7.2

→ Area of ∆ABC = 79.2 cm²

• Hence, the area of ∆ABC is 79.2 cm².

Option (b) 79.2 cm² is the required answer .

Answer 2

Answer:

79.2cm square

Step-by-step explanation:

Area of triangle = 1/2base * height

Base = 22cm

Height = 7.2cm

22 * 7.2 = 158.4

158.4 divided by 2 is 79.2cm

So the answer in 79.2cms square
