Question

if the height of triangle is two times more than the base and the area of triangle is 900 cm then find the base of triangle​

Answer 1

Answer:

Step-by-step explanation:

Let the base of the triangle be x and the height be 2x

Area of triangle = 0.5(x)(2x)

900 = x^2

x = 300 or -300(rej since length cannot be negative)

Base of triangle = 300cm

Answer 2

Answer:

30 cm

Step-by-step explanation:

Area of triangle = l×b÷2

Lenght = 2a

Base = a

Area =900

Subsitute the values

2a×a= 900×2

2a^2 = 1800

a^2 = 900

Sq on b.s

a= 30
