Answer:

A=36

Step-by-step explanation:

Hi love ,

so we now that the are of a triangle is : 1/2bh

the smaller triangle shows that : 9 = 1/2b*3

so b =6

and if the 3 became 6 then 6 will become 12

base of the smaller triangle = 6

base of the larger triangle = 12

Area of Larger triangle = 1/2 * 12*6

= 1/2*72 = 36

A=36
