Question

find the area of the following right angled triangle
1)base=14m, height=17.5m
2)base=12.8cm, height= 6cm
3)base23/4, height 9/2 cm​

Answer 1

1)Area of the triangle

$= \frac{1}{2} \times 14 \times 17.5 = 122.5 {m}^{2}$

2) Area of the triangle

$= \frac{1}{2} \times 12.8 \times 6 = 38.4 {cm}^{2}$

3) Area of the triamgle

$\frac{1}{2} \times \frac{23}{4} \times \frac{9}{2} = \frac{207}{16} = 12.93 {cm}^{2}$

HOPE THIS COULD HELP!!!

Answer 2

1. Area = 1/2 × b × h

= 1/2 × 14 × 17.5

= 122.5 m^2.

2. Area = 1/2 × 12.8 × 6

= 38.4 cm^2

3. Area = 1/2 × 23/4 × 9/2

= 207 / 16

= 12.938 cm^2.
