Question

ABCD ~ QRST
· Find the missing side length, m

Answer 1

Since ABCD ~ QRST

AB/QR = AD/QT

=>6/m= 9/6

=> m = (6×6)/9 = 36/9 = 4

Answer 2

m=4

Explanation

since they are similar triangle .use these ratios

given:AB=6 , AD=9 , QR=m , QT=6

AB/QR=AD/QT

6/m=9/6

do cross multiplication

m*9=6*6

9m=36

m=36/9

m=4

therefore the value of m is 4
