1.	किसी समबाहु त्रिभुज की ऊंचाई 15 cm है। त्रिभुज का क्षेत्रफल ज्ञात करें?A. `50sqrt(3)` sq. cmB. `70sqrt(3)` sq. cmC. `75 sqrt(3)` sq. cmD. `150sqrt(3)` sq. cm
Answer» Correct Answer - C height of equilateral `Delta` `=15cm` `(sqrt(3))/2` (side) `=15` side `=(15xx2)/(sqrt(3))` area `=(sqrt(3))/4("side")^(2)` `=(sqrt(3))/4((15xx2)/(sqrt(3)))^(2)=(sqrt(3))/4xx(225xx4)/3` `=75sqrt(3)cm^(2)`
