Where is the parallelogram?
does it say anything about it being a rhombus?
you made a mark in the lower right hand corner to denote a right angle, but you clearly have a 45 degree angle to the left of that, so which one is it?
That's what the book picture is
i cant draw stright
oh ok, one sec
the problem here is that this has to be a rhombus because if it wasn't then we'd be missing information (namely the base side that runs parallel to the ground), so double check to make sure that nothing is missing
Number 10 hold on
oh i see now
if u can do it Show Work plz
are you familiar with trigonometry?
Nope Only Alg and Geo
We can cut that parallelogram in half along that dashed line to get those two triangles We can then find the base b through the formula b = x/sqrt(2) where x is the hypotenuse In this case, x = 4, so the base is b = 4/sqrt(2) = 2.828 So the perimeter is P = 2*4 + 2*2.828 P = 13.656 So the perimeter is roughly 13.656 meters And the area of one triangle is A = (bh)/2 A = (2.828*2.828)/2 A = 8/2 A = 4 which means that the area of the parallelogram is 2*4 = 8 square meters
tanx a lot
hw will get annoying definitely
Willing to help wit all? 9-19 20-28even
i'm afraid i don't have enough time, which one is really bugging you
idk lol how long do u have
about 10 min or so
ok can u do some if u can
alright, which one do you want me to do?
srry if i seem a pain in the A$$
No you're not a pain at all. # 11 This is a square. And the formula for the perimeter is P = 4s P = 4*5.4 P = 21.6 So the perimeter is 21.6 cm and the formula for the area is A = s^2 A = (5.4)^2 A= 5.4*5.4 A= 29.16 So the area of the square is 29.16 square cm
12? if u have time
Last one and then I have to go # 12 Perimeter: P = 2*15+2*10 P = 30+20 P = 50 So the perimeter is 50 inches Area: A = bc*sin(theta) A = 10*15*sin(45) A = 150*0.70710678 A = 106.066017 So the area is roughly 106.066017 square inches
