You need k by itself, so the only way to do that is to divide both sides by 5
Area of a triangle is 1/2 x base x height:
Area = 1/2 x 8 x 20.5 = 82 square cm.
It is hone-half the area of a rectangle with dimensions 20.5 by 8 cm.
Answer:
1.30
Step-by-step explanation:
3+5x=7
Subtract 3 on both sides, 3 will cancel out on the left side and will subtract by 7 making it 4
5x=4
Then divide by 5 on both sides to isolate the x.
5/4=1.25
1.25 rounds to 1.3

Answer: 3.9ft²
Step-by-step explanation:
Find the area of the rectangle first:
= Length * Width
= 2 * 1.5
= 3 ft²
Find the area of the semi-circle by finding the area of a circle and dividing it by 2:
= πr²
= 3.14 * 1.5/2 * 1.5/2
= 1.76625ft²
Divide by 2:
= 1.76625/ 2
= 0.88 ft²
Add the area of the rectangle to the semi-circle:
= 3 + 0.88
= 3.9ft²
