Question

1 Ratio of the area of two tstiangleş with equal height ię 3:4
If the base of the smaller triangle is
7.5 cm then
what is the corresponding base of the bigger triangle?
→​

Answer 1

Step-by-step explanation:

The ratio of the areas of two triangle with common base =4:3

Height of the larger triangle (h1)=20 cm

Height of the smaller triangle (h2)=?

Area of smaller triangleArea of larger triangle=h2h1 ....[∵ triangles have common base]

⇒34=h220

⇒h2=43×20=15 cm

∴ height of smaller triangle is 15 cm
