Question

the perimeter of two similar triangle ABC and PQR respectively 48 cm and 36 CM if PQ equal to 12 CM then AB is​

Answer 1

Answer:

take two similar triangles first..

then,

PQ / AB

BC / QR

PR / AC = 48/ 36

if PQ = 12 cm

then,

48×12/36

= 13.3

Answer 2

Answer:

The AB = 16 cm.

Explanation:

Adding the lengths of the triangle's sides are done to find its perimeter. For instance, the perimeter of a triangle with sides a, b, and c will be P = a + b + c.

ΔABC =ΔPQR

Perimeter of ΔABC= 48 cm

Perimeter of ΔPQR= 36 cm

We are aware that the ratio of the corresponding sides in two identical triangles is the same as the ratio of their perimeters.

Therefore,

$\frac{Perimeter of triangle ABC}{Perimeter of triangle PQR} = \frac{AB}{PQ}$

Let, AB= x cm

Given that PQ= 12 cm.

Therefore,

$\frac{48}{36} = \frac{x}{12}$

or, 48 ×12 = 36x

or, x= 576/36 = 16

Therefore, AB = 16 cm.
