Answer 1

Step-by-step explanation:

Area of triangle = 1/2 × base × altitude

i. area =

$\frac{1}{2} \times 7.5 \times 4 \\ = 2 \times 7.5 \\ = 15$

15cm^2

ii. Area =

$\frac{1}{2} \times 1.5 \times 0.8 \\ = 1.5 \times 0.4 \\ = 0.6$

0.6 cm^2

Answer 2

area of triangle =

$\frac{1}{2} \times b \times h$

i) 1/2 * 7.5 * 4

= 15 square meter

ii) 1/2 * 1.5 * 0.8

= 6

( * = multiply)
