Question The length of a rectangle is 15 more than 3 times the width. The perimeter is 110. What is the area
Answer: 450 units squared Step-by-step explanation: 2(length)+2(width)=Perimeter W=x Length=15+3w Perimeter=110 2(15+3w)+2w=110 30+6w+2w=110 8w=80 w=10 So: Length is 45 and Width is 10 Area is l*w Area=45*10 Area is 450 units squared Log in to Reply
Answer:
450 units squared
Step-by-step explanation:
2(length)+2(width)=Perimeter
W=x Length=15+3w Perimeter=110
2(15+3w)+2w=110
30+6w+2w=110
8w=80
w=10
So: Length is 45 and Width is 10
Area is l*w
Area=45*10
Area is 450 units squared
