the area of a triangle varies jointly as the base and the height.a triangle with the base of 10cm and the hieght of 12cm has an area 360 square cm.find the area if base is 7cm and the height is 12 cm​

Sagot :

Answer:

A = kbh

360 = (10)(12)k

360 = 120k

3 = k

The resulting equation will be A = 3bh with k = 3

A = 3(7)(12)

= 252 cm²

That's all. Hope it helps.
