Question

the base and the height of are in the ratio 1:3 . its area is 12sqcm.find the base and height ​

Answer 1

________Hey mate________

let the base be X and the height be 3X

Given its Area is 12 cm²

Now, Area of triangle = 1/2× base × height

=> 12 = 1/2 × X × 3X

=> 12×2 = 4X

=> 24 = 4X

=> 4X = 24

=> X = 24/4

=> X = 6 cm

•: base = 6cm

Height = 3x = 3×6 = 18 cm
