find the length of the base of a triangle whose area is 220 m2and altitude is 11m. Share with your friends Share 0 Varun.Rawat answered this We have,base = ?height = 11 cmNow, area of ∆ = 220 cm2⇒12×base×height = 220⇒12×base×11 = 220⇒base = 40 cm 1 View Full Answer Omkar More answered this Area of a triangle = 1/2 x Base x HeightAltitude of triangle = height of the triangle220m2 = 1/2 x Base x 11therefore base = 220 x 2 x 1/11 = 40 mso base = 40mWe can crosscheck by using the formula220 = 1/2 x 40 x 11THEREFORE, LENGTH OF THE BASE IS 40 METERS 1
