PLEASE HELP!!!!A rectangle has a width of 8 m and a length of 7 m.How does the area change when each dimension is multiplied by 5?The area is increased by a factor of 5.The area is increased by a factor of 10.The area is increased by a factor of 25.The area is increased by a factor of 50.

Consider what the area is when a rectangle has a width of 8m and a length of 7m. The area is 8m x 7m, or 56m^2.

Now, multiple the length and width by 5 each, to produce a triangle with the dimensions of 40m and 35m. Multiply the two values together to get 1400m^2.

1400 / 56 = 25, so the area is increased by a factor of 25.
