13 numeric 1 point
suppose you earned 42 points (with bonus questions) out of 40, what percent is that?
answer

Explanation:

Step1: Calculate perimeter of garden

Perimeter formula: $P = 2(l + w) = 2(12.5 + 10) = 2(22.5) = 45$

Step2: Calculate area of garden

Area formula: $A = l \times w = 12.5 \times 10 = 125$

Step3: Find 60% of 40 points

$0.6 \times 40 = 24$

Step4: Find points for 80% of 40

$0.8 \times 40 - 24 = 32 - 24 = 8$

Step5: Calculate percentage of 42/40

$\frac{42}{40} \times 100 = 105$

Answer:

45
125
24
8
105
