Question
From adjoining figure, ∠ABC = 90°, ∠DCB = 90°, AB = 6, DC = 8, then `("A"(Δ"ABC"))/("A"(Δ"BCD"))` = ?

Solution
ΔABC and ΔBCD have same base BC.
∴ `("A"(Δ"ABC"))/("A"(Δ"BCD")) = "AB"/"DC"` ...[Triangles having equal base]
∴ `("A"(Δ"ABC"))/("A"(Δ"BCD")) = 6/8`
∴ `("A"(Δ"ABC"))/("A"(Δ"BCD")) = 3/4`

In the figure, PQ ⊥ BC, AD ⊥ BC. To find the ratio of A(ΔPQB) and A(ΔPBC), complete the following activity.
Given: PQ ⊥ BC, AD ⊥ BC
Now, A(ΔPQB) = `1/2 xx square xx square`
A(ΔPBC) = `1/2 xx square xx square`
Therefore,
`(A(ΔPQB))/(A(ΔPBC)) = (1/2 xx square xx square)/(1/2 xx square xx square)`
= `square/square`
