Question

Base of a triangle is 9 and height is 5. Base of another triangle is 10 and height
is 6. Find the ratio of areas of these triangles.
​

Answer 1

Answer:

Δ1/Δ2= (9×5)/(10×6)

=45/60

=3/4

=3:4

Answer 2

For 1st triangle,

base = 9 cm; height = 5 cm

AREA OF TRIANGLE FORMULA = 1/2* BASE*HEIGHT

Area of 1st triangle = 1/2 *9*5

= 45/2 cm^2

For 2nd triangle,

base = 10 cm; height = 6 cm

Area Of 2nd Triangle = 1/2*base*height

= 1/2*10*6

= 30 cm^2

RATIO OF AREAS OF 1ST TRIANGLE TO THE OTHER = 45/2 /30 = 45/60 = 3:4

HENCE THE RATIO OF AREAS IS 3:4
