Question

Height of five people A, B, C, D, E are given as follows:
165 cm, 1.8 m, 72 inches, 5.9 feet, 2.1 yards
Arrange A, B, C, D, E in ascending order.

Given:
(1 yard = 3 feet
1 feet = 12 inches
1 inch = 2.54cm)

Answer 1

We know $1$ m = $100$ cm
$1$ cm = $\frac{1}{100}$ m
$1$ yard = $3$ feet = $3$ x $12$ inches = $36$ inches
$36$ inch = $36$ x $2.54$ cm = $91.44$ cm

$1$ yard = $91.44$ cm
$1$ feet = $30.48$ cm

Height of A = $165$ cm
Height of B = $180$ cm
Height of C = $72$ inch = $72$ x $2.54$ cm = $182.88$ cm
Height of D = $5.9$ feet = $5.9$ x $30.48)cm=179.832$ cm

Height of E = $2.1$ yard = $3\times 2.1$ feet = $6.3$ x $30.48)cm=192.024$ cm

Height of A, B, C, D, E in cm are $165,180,182.88,179.832,192.024$
So, ascending order: A, D, B, C, E
