Question

2) In ABC, D is a point on BC, if the area of ABD is 20 sq cm
and the area of ACD is 25 sq cm then
a) What is the ratio of the areas of ABD and ACD ?
b) What is the ratio of BD and DC ?​

Answer 1

Answer:

ACB is the answer of question

Answer 2

Answer:

THE RATIO OF ABD AND ACD IS 4:5

Step-by-step explanation:

sol?:

here,according to question:

area of ABD = 20 sq.cm ..........(let it be denoted as A1)

area of ACD = 25 sq.cm ..........(let it be denoted as A2)

then;

ration of area of ABD AND ACD = A1:A2

                                                       = 20:25

                                                       = 4:5 ans,

now ,

let the length of BC = x cm , BD = y cm

Then,

ratio of BD : DC = y/(x-y) ans
