Question

The side of the triangle are 7/2 cm, 11/4 cm, and 16/5 cm, Find the Perimeter​

Answer 1

Answer:

189/20 cm is th perimeter.

Answer 2

Side of triangles:

a= 7/2cm

b= 11/4cm

c= 16/5cm

Perimeter= a+b+c

$= \frac{7}{2} + \frac{11}{4} + \frac{16}{5}$

$= \frac{7(4 \times 5) + 11(2 \times 5) + 16(2 \times 4)}{2 \times 4 \times 5}$

$= \frac{7(20) + 11(10) + 16(8)}{40}$

$= \frac{140 + 110 + 128}{40}$

$= \frac{378}{40}$

$= 9.45cm$

Perimeter=9.45cm
