Question

Question no 6 .it's urgent ..

Answer 1

1 area of triangle= 1/2 b*h
= 1/2*6*4.5
=13.5cm^2
2 1/2 b*h
= 1/2*5*3.2
=8 cm^2
3 1/2 b*h
= 1/2 3*2.8
= 3.2 cm ^2

Answer 2

Answer:

(i) 13.5 cm²

(ii) 8 cm²

(iii) 4.2 cm²

Step-by-step explanation:

Formula of Triangle - $\frac{1}{2}bh$

(i) Given Values -

• b = 6 cm
• h = 4.5 cm

Now fill in the values for b and h

$\frac{1}{2} * 4.5 * 6$

A = 13.5 cm²

(ii) Given Values -

• b =  5 cm
• h = 3.2 cm

Now fill in the values for b and h

$\frac{1}{2} * 3.2 * 5$

A = 8 cm²

(iii) Given Values -

• b =  3 cm
• h = 2.8 cm

Now fill in the values for b and h

$\frac{1}{2} * 2.8 * 3$

A = 4.2 cm²
