Hello, Buddy!!

ɢɪᴠᴇɴ:

• ∆ABC & ADB are adjoining figures in which BC⊥AB & AD⊥AB
• Length of BC = 4
• Length of AD = 8

ᴛᴏ ꜰɪɴᴅ:

• ar(∆ABC)/ar(∆ADB)

ʀᴇQᴜɪʀᴇᴅ ꜱᴏʟᴜᴛɪᴏɴ:

WKT

Area of Triangle ☞ 1/2×Height×Base

Here, Altitudes of ∆ABC and ∆ADB are BC & AD.

→ (1/2×BC×AB)/(1/2×AD×AB)

→ (1/2×4×AB)/(1/2×8×AB)

By Cancellation of AB & 1/2

→ 4/8

→ 1/2

• ar(∆ABC)/ar(∆ADB) = 1/2
