Question

Areas of two similar triangle are 144cm^2and 81cm^2.If one side of the first triangleis 6cm then find the corresponding side ofthe second triangle

Answer 1

let the corresponding side of second triangle be x cm
144/81=(6/x)^2 (by area theorm)
(12/9)^2=(6/x)^2
12/9=6/x
x=9/2
x=4.5 cm
therefore,the corresponding side of second triangle is 4.5 cm
hope it helps!!
