1. P
Answer:
Width = 45
Step-by-step explanation:
- Formula of the perimeter of a rectangle is p=2(l+w). What you need to do is replace the values.
210=2(60+w)
210=120+2w
210-120=2w
90=2w
w=45
Checking
p=2(60+45)
p=2(105)
p=210
2.
Answer:
90 times
Step-by-step explanation:
- A volleyball court is a rectangle which means that the length and the wind of the parallel lines are congruent.
2(18)+2(6)=36+12=48
- Divide the total number of covered meters by 48.
4,320÷48 = 90
3.
Answer:
Php 10,200
Step-by-step explanation:
- Use the formula of the perimeter of a rectangle to get the total number lf cloth per square meter.
p = 2(45+15)
p = 2(60)
p = 120
If one square meter costs Php 85 multiply 120 by 85
85(120)= 10,200
