Answer:

The area of a right angle triangle is A = 63.635

Step-by-step explanation:

<u>Step:-1</u>

By using area of the triangle formula is A = \frac{1}{2}(base)(height).......(1)

Given base of the triangle is (b) = 14.3

Given height of the triangle is (h) = 8.9

<u>Step:- 2</u>

substitute b and h values in formula in equation (1)

A = \frac{1}{2}(14.3)(8.9)

on simplification, we get the area of the triangle is 63.635

<u>Final answer</u>:-

The area of the triangle is A= 63.635

Q 1.) Expand using identities:<br>i. (a+2b)²<br>ii. (5x-3y)²<br>iii. (3a+4)(3a-4)(9a²+16)<br>​
Ganezh [65]

Step-by-step explanation:

#1.

(a + 2b)²

<em>Using identity (x + y)² = x² + 2xy + y², we get:</em>

= (a)² + (2b)² + 2 × (a) × (2b)

= a² + 4b² + 4ab

= a² + 4ab + 4b² Ans.

#2.

(5x - 3y)²

<em>Using identity (a - b)² = a² - 2ab + b², we get:</em>

= (5x)² + (3y)² - 2 × (5x) × (3y)

= 25x² + 9y² - 30xy

= 25x² - 30xy + 9y² Ans.

#3.

(3a + 4)(3a - 4)(9a² + 16)

<em>Using identity (x + y)(x - y) = x² - y², we get:</em>

= [(3a)² - (4)²][9a² + 16]

= (9a² - 16)(9a² + 16)

= (9a²)² - (16)²

= 81a⁴ - 256 Ans.
