Question

A triangle has a base of 10cm,if the height is 2x m and the area is 80x^2sq.m.find the area and the height of the triangle​

Answer 1

Answer:

Area =1/2bh

$b = 10 \\ h = 2x\\area = 80 {x}^{2} \\ 80 {x}^{2} = \frac{20x}{200} \\ 8 {x}^{2} = 0.10x \\ x = \frac{1.0}{80}$

hence height is 2*1/80= 1/40 m

area is 80 m^2
