Answer:
(2a -
)(2a +
)
Step-by-step explanation:
4a² -
← is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
4a² - 
= (2a)² - (
)²
= (2a -
)(2a +
)
Answer:
200 sq units
Step-by-step explanation:
As you might know, 3 angles of a triangle adds up to 180*. Since you already know the angles are 60* there is one more 60*. So by this you know that all the sides are equal.
As the given states, one side is 20. So following the standard way to get the area of a triangle b*h/2; 20*20 = 400 / 2 = 200 sq units
