See the picture attached to better understand the problem
we know that
Applying the Pythagoras Theorem
AC²=AB²+BC²-----> AC²=5²+9²----> AC²=25+81----> AC²=106
AC=√106 units
the length side of the square is equal to the hypotenuse
so
b=√106 units
where b is the length side of the square
area of the square=b²-----> (√106)²-----> Area=106 units²
the answer is
106 units²

Answer:
$90, $135, $189
Step-by-step explanation:
Since the first part of the ratio is two- thirds of the second, then
first part = × 5 =
The ratio is then
: 5 : 7
Sum the 3 parts of the ratio
+ 5 + 7 =
Divide the amount to be shared by the sum to find the value of one part of the ratio.
$414 × = $27 ← value of 1 part of the ratio, then
× $27 = $90
5 × $27 = $135
7 × $27 = $189
The 3 parts are $90, $135, $189
