Question

In figure, ∠ABC = ∠DCB = 90º; AB = 8 units, DC = 10 units. A (△ABC)A (△DCB) = ?
​

Answer 1

Answer:

≅6/8

Step-by-step explanation:

given that:-

<ABC = 90°

so the area of triangle

= 1/2(base × perpendicular height

=> area of ∆ABC = 1/2(AB × BC)

=> 1/2(6 × BC)

similarly,

<DCB = 90°

area of ∆DCB= 1/2(8 × BC)

NOW,

(area of∆ABC) / (area of ∆DCB) = [1/2(6 × BC) / 1/2(8 × BC)]

=> (6×BC)/(8×BC)

=> 6/8
