Question

find the base of a triangle whose height is 20cm and area is 150cm²​

Answer 1

Answer:

a=150cm^2

height =20cm

base =?

therefore area=1/2×b×h

150=1/2×b×20

150×2÷20=b

15cm=b

Answer 2

Answer:

The area of a triangle = 1/2 × b× h

height = 20cm

Area = 150 cm^2

According to the question,

= I/2 × b × h = Area

= 1/2 × b × 20 = 150

= 10b = 150

= b = 150/10

= b = 15

So, the base of the triangle is 15cm
