=1/2×(x)×(2x)

⟹x

2

=

400×2

=400cm

⟹x=20cm

So,

base=20cm;height=40cm

Answer 2

Answer:

20cm;40cm

Step-by-step explanation:

Area of a triangle=1/2×base×height

let, base= x cm , then height = 2x cm

So, 400cmsquare = 1/2×(x)×(2x)

⟹ xsquare = 400×2 / 2 = 400cm

⟹ x = 20cm

So,

base = 20cm; height =40cm
