Answer:
312cm2
Step-by-step explanation:
Area of the triangles:
A =1/2bh
A=1/2(10*12) = 1/2*120=60.
There are two triangles. 60*2=120. 120 is the area of both triangles.
Area of the rectangle:
16*12=192.
120+192=312cm2

Step-by-step explanation:
The square mural in Olivia's classroom has dimensions x by x.
Then she paints a mural of dimensions: x+5 (the length) by x-2 (the width).
Thus the second mural (the hallway mural) has the shape of a rectangle with dimensions (x+5) by (x-2), so the area of the second mural is
(x+5)(x-2).
<span>
each side of the classroom mural is 7 feet means that x = 7 ft,
</span>
thus the area of the hallway mural is :
(x+5)(x-2)=(7+5)(7-2)=12*5=60 (square feet)
Answer:
<span>C. (x + 5)(x – 2); 60 square feet</span>
Just take them separately. so how many 6 oz glasses can you fill?
1284/6 = 214
how many 12 oz glasses?
1284/12 = 107
then find the difference between the two
214-107= 107
107 more glasses can be filled
