Answer:
l = 10.5 cm and A = 21 cm2
Step-by-step explanation:
Area is w*l
Perimeter is 2(w+l)
Replacing the information known in the problem you can get the length with the perimeter
P = 2(w+l)
25 = 2(2+l)
12.5 = 2 + l
10.5 cm = l
with the length now you can find the area
A = w*l
A = 2*10.5
A = 21 cm2
B. line 2
hope this helps :D
Answer:
I'm pretty sure it's 4.3?
Step-by-step explanation:
Because you divide the larger triangles side first because you are figuring out the scale factor of the small triangle to the larger triangle, not the other way around.
Sorry if i'm wrong
2.1-2p= -4.7
they said the difference of 2.1 and twice a number p. which I'm assuming letter p, but anyway. difference means subtraction and twice mean multiplication so 2p
that's why we have 2.1-2p= -4.7
Yes that is the correct answer
