Learning from Maria Sharapova's Advice for the Young & Successful mapped by Lim Liat 30 May 2015 "At that age it's tough. You have so many opportunities and they are so much fun, especially at a young age. "To be part of great events and meet stars and to be part of a Vogue photo shoot, those are really cool things for a young girl and I did enjoy them. Get, Be & Listen to Smart Mentors Watchout for the Temptations! Have fun but have control So many lost their ways and lives! Remember the foundational reason for your success.

Sanjiv Aswin 1 year, 11 months ago

Certainly! Blood consists of several components, including: 1. **Red Blood Cells (RBCs or erythrocytes):** Responsible for carrying oxygen from the lungs to the rest of the body and transporting carbon dioxide back to the lungs to be exhaled. 2. **White Blood Cells (WBCs or leukocytes):** These cells are part of the immune system and help in fighting infections and diseases. There are different types of WBCs, such as neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each with its specific role in defending the body. These two types of cells are the primary cellular components of blood, along with platelets, plasma, and various proteins, ions, and nutrients essential for bodily functions.

Shourya Deep 1 year, 11 months ago

Let the equal side be 'a' and base be 'b', then its perimeter = 2a + b Let 'a' be 3k and 'b' be 2k. A/Q Perimeter = 32cm. ⇒2×3k + 2k = 32cm ⇒8k = 32cm ⇒k= 4cm. Hence, sides of triangles are 12cm, 12cm and 8cm. a=12 cm b=8cm Now, area of isosceles triangle= (b/4) × √(4a²–b²) = 2× √(4×144–64) = 2× √(576–64) = 2× √(512) =2× 16√2 =32√2 Hence, area of triangle is 32√2cm².
