3w)w = 24in^2 (Tossing out the negative solution for unit measure)
3w^2 = 24
w^2 = 8
w = 2√2in and L = 6√2in L+=+3w
P = 2L + 2w = 16√2in
Answer:
w=7 and l=10
Step-by-step explanation:
To find the dimensions, create an equation for its perimeter and solve. Recall, the perimeter formula for a rectangle is P = 2l+2w. P is 34 cm. L is 4cm less than twice the width or 2w-4. And the width is w.
P = 2l+2w
34 = 2(2w-4) + 2w
34 = 4w -8 +2w
34 = 6w -8
34+8 = 6w
42 = 6w
7=w
The width is 7 cm. To find the length substitute w=7 into l=2w-4.
l=2w-4
l=2(7)-4
l=14-4
l=10
Answer: 4, -4

If theres on at all then ~ C 6-8 however it seems that theres not one tbh
