If the rectangle is englarged using a scale factor of 2 what will be the perimeter and area of the new rectangle

The perimeter will be enlarged by 2 and the area is enlarged by 4.

Step-by-step explanation:

The perimeter is the distance around the rectangle. If the side lengths are enlarged by 2 then the distance around the shape will be enlarged 2.

The area of a rectangle is A = L*W. If the the L and W are doubled then the

A = 2L*2W = 4L*W

So the area is enlarged by 4.

(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
