Question

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:

$area \: of \: triangle \: 1 = \frac{1}{2} \times 9 \times 5 \\ = 22.5 \\ area \: of \: triangle \: 2 = \frac{1}{2} \times 10 \times 6 \\ = 30 \\ ratio \: of \: triangle \: 1 \: to \: triangle \: 2 \\ = 22.5:30 \\ = 11.25:15 \\ = 0.75:1$

Answer 2

Step-by-step explanation:

1st triangle

base=9

height=5

Area of triangle =1/2×b×h

=1/2×9×5

=45/2 or 22.5

2nd triangle

base =10

height=6

area of triangle =1/2×b×h

=1/2×10×6

=30

Ratio of 1st and 2nd triangle is 22.5:30
