Question

If the triangle ABC is similar to the triangle PQR, area of the triangle ABC = 100 square centimeters, area of the triangle PQR = 144 square centimeters and QR = 6 cm, then length of BC is *

a).10
b).5
c).20
d).12

Answer 1

Answer:

the length of BC is 5 cm

Step-by-step explanation:

because the ratio of the sides is √100 : √144

= 10 : 12

so the let the value be x cm

so ... x/6 = 10/12 ... therefore x = 5 cm
