Question

The length of a rectangle is 15 more than 3 times the width. The perimeter is 110. What is the area

Answer 1

450 units squared

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
