Question

a. From any point in the interior of trian-
gle, lines are drawn parallel to the sides
of it. If the area of the three small tri-
angles thus formed 25, 64 and 100 square units find the area of triangle​

Answer 1

Answer:

please brainlist answer

Step-by-step explanation:

All these triangle formed will be similar as each triangle is similar

to Δ ABC

Area of triangle are 4 , 9 , 16

So sides of these small triangle will be in the ratio of

2 : 3

2 : 4

3 : 4

2 + 3 = 5

2 + 4 = 6

3 + 4 = 7

5² - (4 + 9 ) = 12

6² - (4 + 16)  = 16

7² - (9 + 16) = 24

Area of Δ ABC = 12 + 16 + 24  + 4 + 9 + 16

= 81

Area of Δ ABC = 81 sq units
