Suppose the length and the width of the sandbox are doubled.
zalisa [80]

The percentage change in perimeter is 100%.

The percentage change in area is 300%

<h3>How to find perimeter and area?</h3>

The perimeter of the sandbox = 2l + 2w

where

  • l = length
  • w = width

Therefore,

perimeter = 2(10) + 2(6)

perimeter = 20 + 12 = 32 ft

The area of the sand box = lw

area = 10 × 6 = 60 ft²

If the length and width are doubled,

length = 2(10) = 20 ft

width = 2(6) = 12 ft

hence,

perimeter = 2(20) + 2(12) = 40 + 24 = 64 ft

area = 12 × 20 = 240 ft²

Therefore,

percentage change in perimeter = 64 - 32 / 32 × 100 = 100%

percentage change in area = 240 - 60 / 60 × 100 = 18000 / 60 = 300%

Find the value of x.
andrezito [222]
X = 57.  Use the rules for inscribed angles.  If that exterior angle is 123, then its supplement is 57.  That 57 degree inscribed angle has an intercepted arc that is also the same arc that angle x intercepts.  So x has the same measure as the other inscribed angle.  Your answer is B.
