Answer:
The width of the logo need to be 15 cm.
Step-by-step explanation:
Since the logo is a rectangle, it's area is given by the product of the width and the length.
Area = width*length
Since the width is an unkown value we will call it "x" and the length is twice the width so it'll be "2*x". The area of the logo is:
Area = x*(2*x) = 2*x²
In order to have a patch that is 450 cm² we need:
2*x² = 450
x² = 450/2 = 225
x = sqrt(225) = 15 cm
The width of the logo need to be 15 cm.
Answer:
-7
Step-by-step explanation:
You divide -3 on both sides to get the variable by itself, so -3 divided by 21 is -7
1/2 (Base x height) = area
1/2 (4*x)=10
2x=10
X=5
The height is 5 units
