Question

what will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 3.5? 6 cm 8 cm perimeter = 98 cm area 588 cm perimeter = 42 cm area 109.25 perimeter = 42 cm area 588 perimeter = 98 cm area 109.25

Answer 1

LSF=3.5
Area scale factor=
`LSF^(2)`
ASF=
`3.5^(2)`
ASF= 12.25
New area=original area* ASF
=588*12.25
=7203 square units

New perimeter= Original perimeter * LSF
New perimeter= 343 units
