Lobby a hotel lobby measures 40 yards
by 60 yards. find the area and
perimeter of the lobby's floor.

Area is 2400 and perimeter is 200

Step-by-step explanation:

Area is width times length so 40*60 (2400)

Perimeter is 2*(length+width) so 2(40+60) which is 200

Area: 2400 yards

Perimeter: 200 yards

Step-by-step explanation:

40*60=2400

Area=2400 yards

60+60+40+40=...

120+80= 200

Perimeter= 200 yards

-Good luck!-

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
