Question

The length and breadth of a rectangle are 6 cm and 4 cm respectively. Find the height of the triangle whose base is 6 cm and area is three times that of the rectnagle

Answer 1

Answer:

h = 8/3 or

h =2.66666..............

Step-by-step explanation:

area of rectangle = 6*4= 24cm^2 ( area=l*b)

let height = h

area of the triangle = 1/2*6*h = 3*h (area = 1/2*b*h)

now given area of triangle is 3 times the area of rectangle

so 3*3h=24

9h=24

h = 24/9

h = 8/3

h =2.66666..............

Answer 2

12 cm

Step-by-step explanation:

area of the rectangle = 6×4

therefore, 3 × area of the rectangle = 3 ×6×4 = 72 sq cm

let the height be h

therefore

1/2 × 6 × h = 72

or, 3h = 72

or, h= 72/3

or, h = 24
