Answer :
Answer:
238 cm
Step-by-step explanation:
so we have a scale factor of 17: 1
originally we had the dimensions: 3cm by 4m
now we have 3*17 by 4*17 = 51 cm by 68 cm
Perimeter = 2*51 + 2*68 = 238 cm
The perimeter of the rectangle in the magnified image is 238 cm.
What is a rectangle?
'Rectangle is a two-dimensional shape in which the opposite sides are parallel and equal to each other and all four angles are right angles.'
According to the given problem,
Length of the triangle = 3 cm
Width of the triangle = 4 cm
In the magnified image, 1 cm = 17 cm
⇒ 3 cm = ( 17 × 3 ) cm
= 51 cm
⇒ 4 cm = ( 17 × 4 ) cm
= 68 cm
Length of rectangle in magnified image = 51 cm
Width of rectangle in magnified image = 68 cm
Perimeter of the rectangle in magnified image = {2 × ( length + width )} cm
= = {2 × ( 51 + 68 )} cm
= ( 2 × 119 ) cm
= 238 cm
Hence, we can conclude, the perimeter of the rectangle in the magnified image is 238 cm.
