In the figure `BC_|_AB, AD_|_AB,BC=4,AD=8`, then find `(A(DeltaABC))/(A(DeltaADB))`.

Text Solution

Verified by Experts

`BC=4`, `AD=8` ….. (Given)
`DeltaABC` and `DeltaADB` have same base `AB`.
Areas of triangles with same base are proportional to their corresponding heights.
`:.(A(DeltaABC))/(A(DeltaADB))=(BC)/(AD)`
`:.(A(DeltaABC))/(A(DeltaADB))=(4)/(8)` `:. (A(DeltaABC))/(A(DeltaADB))=(1)/(2)`
