Answer:
x = 25 ft
Step-by-step explanation:
here we see the student standing and creating a small triangle that is equivalent to the big triangle since it has the same angles, the only difference is that its smaller, so what we have to do is make a proportion of both triangles, so since 8 ft correspond with the 40 ft they're going to be in the same part of the proportion and the other measurements, including x, on the other part, so itll be 5/8 and x/40, see how the 8 and 40 are both on the bottom? thats because they correspond, so now all you have to do is cross butterfly, so you can set up an expression on 8x= 5*40 or you can just multiply 5*40 and then divide by 8, your answer will be x= 25 ft
Answer:
a) Perimeter of old garden=6w+8
b) A = 2W^2+4W
Step-by-step explanation:
old Area = length * width
= L * W
the old perimeter = half of the new one, so it is 6w+8
the old perimeter has to equal 2L + 2W
2L+2W=6W+8
2L=4W+8
L=2W+4
Area=L*W
so
A=(2W+4)(W)
=2W^2+4W
