Question

The base and height of a triangle are in the ratio 3 : 4, if the area of triangle is 294cm2

. Find its base and height​

Answer 1

Answer:

21 and 28 cm ....hope it helps u

Answer 2

Answer:

let the height and base be 3x and 4x

area is given= 294 cm^2

area of a triangle= 1/2 × base × height

294 cm^2 = 1/2 ×3x × 4x

294 × 2 = 12x^2

588 = 12x^2

588/12 = x^2

49 =x ^2

√49 = x ^2

7cm = x

base = 3x = 3 × x = 3 × 7 = 21 cm

height = 4x = 4 × x = 4 × 7= 28 cm

therefore, base of triangle = 21 and height = 28 cm
