Solved Example on Reduce
Ques: The length of each side of a square field is 12 yd. If each of its sides is reduced to half, what would be the area of the resulting field?
Choices:
A. 38 yd2
B. 36 yd2
C. 32 yd2
D. 34 yd2
Correct Answer: B
Solution:
Step 1: The length of each side of the square field is 12 yd
Step 2: The length of each side of the field after reducing it to half = 12 × 1/2= 6 yd
Step 3: The area of the square field = side × side [Formula for area.]
Step 4: = 6 × 6 [Substitute the value of side.]
Step 5: = 36 yd2 [Simplify.]
Step 6: The area of the resulting field would be 36 yd2
Quick Summary
- Reduction involves decreasing a value.
- It can apply to physical objects or numerical values.
