Area of the square = 6 * 6 = 36
area of 1 triangle = 1/2 x 6 * 4 = 12
area of 4 triangles = 4 * 12 = 48
total area = 36 +48 = 84 sq. cm
5 x 3 = 15 is this correct
Answer:
it's the 4th answer.
Step-by-step explanation:
yeah-ya...... right?
Perimeter is the sum of all sides.
In this case:
a)
Perimeter=(x-2)+(2x-6)+(3x-9)
b)
perimeter=(<span>x-2)+(2x-6)+(3x-9)
perimeter=(x+2x+3x)+(-2-6-9)
perimeter=6x-17
c)
if x=6
</span><span>perimeter=6x-17
</span>perimeter=6*6-17=36-17=19
perimeter=19
