(Theres 2 triangles, RST with a base of 18 cm and height of 9 cm, and JKL, with a base of 12 cm and height of x cm.)

Answer 1

Please explain

Answer 2

the area of a triangle = 1/2 * base * height

Answer 3

Do the triangles have the same areas?

Answer 4

for jkl base = 12 and height = h

Answer 5

no, RST has a height of 9 cm and a base of 18 cm, JKL has a height of unknown cm and base of 12 cm.

Answer 6

* height = x

Answer 7

1/2 * Base * Height is the area:
6x is the area

Answer 8

I think i know the answer, H, first use 9/18 =12/h and then use are= 1/2 (12h)

Answer 9

sorry my pc is slow
