Question

1. For any triangle, complete the following table.
(i) (ii) (iii) (iv) (v) (vi) (vii)
base 168 5 x 6 ? ?
height 1014 20 2x ? 5 11
area ? ? ? ? 30 50 110​

Answer 1

Answer:

we know,

area of a triangle= 1/2 (base * height)

⇒height= 2area/base

⇒base= 2area/ height

i) area= 1/2(6 * 10)=30

ii) area= 1/2(8*14)=56

iii) area=1/2(5*20)=50

iv) area=1/2(x*2x)=x²

v) height=(2*30)/6=10

vi) base=(2*50)/5=20

vii) base=(2*110)/11=20
