GIVEN :-

  • Height of the triangle is 18 cm.
  • Area of the triangle is 72 cm².

TO FIND :-

  • The base of the triangle.

SOLUTION :-

Area of triangle = 1/2 (base × height)

72 cm² = 1/2 (base × 18 cm)

72 cm² = base × 9 cm

base = 72 cm²/9 cm

base = 8 cm

Hence The base of triangle is 8 cm.

VERIFICATION :-

☞ Area of triangle = 1/2 (base × height)

72 cm² = 1/2 (8 cm × 18 cm)

72 cm² = 144 cm²/2

72 cm² = 72 cm²

L.H.S = R.H.S
