Question

find the altitude of a triangle whose base is 20cm and is 150cmFind the altitude of a triangle whose base is 20 cm and area is 150 cm square. ​

Answer 1

Answer:

let the altitude be Xcm

Then area of triangle = 1/2bh

150cmsq = 1/2×20×x

150cmsq = 10×x

150cmsq/10cm=x

15cm = x

Answer 2

Answer:

Step-by-step explanation:

Area of a Triangle = (base × Altitude) ÷ 2

150 = ( 20 × Altitude) ÷ 2

150 × 2 = Altitude ×20

300 ÷ 20 = Altitude

15 cm = Altitude
