15%=0.15
160*0.15=24
Answer:
8%
Step-by-step explanation:
Original perimeter is 100cm
- The 20cm is representative of the width
- 30cm is representative of the length
length is increased by 10%
- 30+(.10 x 30)
- (1 + .10) × 30
- (100% + 10%) × 30
- 110% × 30
- 110 ÷ 100 × 30
- 110 × 30 ÷ 100
- 3,300 ÷ 100
- = 33
length is increased by 5%
- 20 + (5% × 20) =
- 20 + 5% × 20 =
- (1 + 5%) × 20 =
- (100% + 5%) × 20 =
- 105% × 20 =
- 105 ÷ 100 × 20 =
- 105 × 20 ÷ 100 =
- 2,100 ÷ 100 =
- = 21
New perimeter: 108 cm
Percentage increase:
- (108-100):100*100 =
- (108:100-1)*100 =
- 108-100 = 8
- = 8%
Hopefully this helps
I think it is distributive property maybe i’m not too sure
