Find the area of each of the following triangles:

(a)

(b)

(c)

(d)

(a) It is given in the question that,

Height of triangle = 3 cm

Base of triangle = 4 cm

We know that,

Area of triangle = × Base × Height

= 6 cm^{2}

∴ Area of triangle is 6 cm^{2}

(b) It is given in the question that,

Height of triangle = 3.2 cm

Base of triangle = 5 cm

We know that,

Area of triangle = × Base × Height

= 8 cm^{2}

∴ Area of triangle is 8 cm^{2}

(c) It is given in the question that,

Height of triangle = 3 cm

Base of triangle = 4 cm

We know that,

Area of triangle = × Base × Height

= × 4 × 3

= × 12

= 6 cm^{2}

∴ Area of triangle is 6 cm^{2}

(d) It is given in the question that,

Height of triangle = 2 cm

Base of triangle = 3 cm

We know that,

Area of triangle = × Base × Height

= × 3 × 2

= × 6

= 3 cm^{2}

∴ Area of triangle is 3 cm^{2}
