Question

04 (A) Solve the following Questions:
10
1) Base of a triangle is 9 cm and height is 5 cm Base of another triangle is 10 cm and
height is 6 cm. Find the ratio of Areas of these triangles.​

Answer 1

Step-by-step explanation:

Area of triangle is ½ ×base×height

area of 1st triangle = ½×9×5

22.5 cm²

Area of second triangle = ½×base×height

= ½×10×6

30cm²

Ratio = 22.5:30

4.5:6

1.5 : 2

Answer 2

Answer: let ,

ratio of first triangle be b¹ = 9 ,h¹= 5

ratio of another triangle be b²= 10 ,h²=6

formula :

ratio of first triangle =¹/² b¹×h¹ =¹/²9×5 =22.5cm²

ratio of another triangle =¹/²b²×h²

=¹/²10×6

=30 cm² =22.5:30

= 4.5:6 =1.5:2

.thereforeRatio of. area of triangle

=1.5:2
