Answer:
width is = 26ft
length is = 31ft
Step-by-step explanation:
The area of hall is 806 sq. ft.
length is 5 ft greater than its width.
L = 5+b
L*b = 806
(5+b)*b= 806
5b +b² = 806
B²+5B-806= 0
Solving quadratically
B² +31B -26B -806= 0
B(B+31)-26(B+31)= 0
(B-26)(B+31)= 0
B= 26 or -31
So the value of the width must be positive so the width is = 26ft
If width is 26, length is 26+5 = 31ft

Answer:
a right triangle
is equal to
Step-by-step explanation:
Pythagorean's theorem is a²+b²=c² with c being the longest sides. If it is true then it is a right triangle.
<u>18²</u> + <u>24²</u> = <u>30²</u>
324+576=900
This is true so the triangle is a right triangle
A’B’C’D’ is obtained by translating ABCD 3 units to the right (i.e. a positive translation of 3 units along the x axis) and 5 units down (i.e. a negative translation of 5 units along the y axis).
So, in order to go back to ABCD, we have to invert both translation: we have to go 3 units to the left (i.e. a negative translation of 3 units along the x axis) and 5 units up (i.e. a positive translation of 5 units along the y axis).
