Answer :
L1= 10 ft
W1=4 ft
L2=L1*(3/2)
W2=W1*(3/2)
L2=10 ft times (3/2) = 15 ft
W2 = 4 ft times (3/2) = 6 ft
The new dimensions of the poster after enlargement by a scale factor of 3/2 are:
- length = 15 feet
- width = 6 feet
Recall:
To enlarge a shape by a scale factor, multiply each of the dimension of the shape by the scale factor.
Thus, the dimensions of the given rectangle are:
- length = 10 feet
- width = 4 feet
New dimensions of the poster after enlargement by a scale factor of 3/2:
- length = 10 × 3/2 = 15 feet
- width = 4 × 3/2 = 6 feet
Therefore, the new dimensions of the poster after enlargement by a scale factor of 3/2 are:
- length = 15 feet
- width = 6 feet
