Question

Practice set 1.1
1. 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:

3/4

Step-by-step explanation:

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

So in triangle 1 ,

b1 = 9

h1 = 5

And in triangle 2,

b2 = 10

h2 = 6

Now,

Area of triangle 1 = 1/2 × 9 × 5 = 45/2

Area of triangle 2 = 1/2 × 10 × 6 = 30

Ratio of area of triangle 1 to triangle 2 ,

Area of triangle 1 / Area of triangle 2 = 45/2 × 1/30 = 3/4
