The length of a rectangle is 5m longer than its width if the perimeter of the rectangle is 150m find its width and area

Question

Finding The width and areas of rectangles Grades 9

Answer 1

Perimeter=2(length+width)=150, so l+w=75 and 2w+5=75, w=70/2=35m, l=40m.

CHECK: perimeter = 2*75=150m. Length=40m, width=35m.

Answer 2

Hi, yes I'm just not sure what you're trying to solve here I've learned this a few days ago and I don't exactly remember what the formula is. Isn't it A = bh? Or is it A = 1/2bh? I just don't know I mean remember, I'm not trying to back out on you though okay? Really I'm not, I'm just really bad at this kind of math I've got 5 questions like this could you help me with them? I'm horrible at this kind of area stuff.........
