Over 97% would be dividing
The answer is A because 2+1 equals 3 m+m equals 2m
Looking at a number in different ways can help understand it’s application better. For example, giving an answer with radicals(square roots) is precise, but it’s not practical because you really don’t know what that number means.
Step-by-step explanation:
width of rectangle(w)=x let
length (l)=4x
perimeter of rectangle=70
2(l+w)=70
2(4x+x)=70
8x+2x=70
10x=70
x=70/10
x=7
again,
- length =4x=4×7=28cm
- width=x=7
area of rectangle =l×w
hope it helps.
