Use the Pythagorean theorem: c2 = a2 + b2, in this example we need to know, let's say a. So that,
x2 = c2 - b2
x = √(212 - 72)= √(441 - 49) = √392 = √196*2 = 14√ 2
The area of a parallelogram is calculated by multiplying the length of the base by the height. In this case, the base is 3 feet and the height is 7 feet. Therefore, the area of the parallelogram is 3 feet * 7 feet = 21 square feet.
No, not all triangles with a base of 7 cm will have an area of 21 cm². The area of a triangle is calculated using the formula ( \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} ). For a triangle with a base of 7 cm to have an area of 21 cm², the height must be 6 cm, but if the height varies, the area will also change accordingly.
7. Since the area of a rectangle is base x height, the base must be the area (28) divided by the height (4). 28/4 = 7
1 Let the height be x+1.75 and the base be x 2 1837.5 sq mm is the same as 18.375 sq cm 3 0.5*(x+1.75)*x = 18.375 => x2+1.75x-36.75 = 0 4 Using the quadratic equation gives x a positive value of 5.25 5 Therefore: height = 7 cm and base = 5.25 cm 6 Using Pythagoras: hypotenuse = 8.75 cm 7 Perimeter: 8.75+7+5.25 = 21 cm
1/2*(7+11)*height = 63 18*height = 126 height = 7 units of measurement

The area of a triangle is calculated using the formula: Area = 1/2 * base * height. Substituting the values given, the area of the triangle would be: 1/2 * 7 inches * 6 inches = 21 square inches.
You can use reverse Pythagorean theorem 11.2 squared is 125.44. Subtract that from the hypotenuse squared (49), and you get the height squared. Find the square root of that number nad Bingo! You have the height. ( In case you don't actually wan't to do the math, its approx. 8.742997198 units)
The volume of a square pyramid with height 7 and base 5 is 58.33 cubic units.
A cone with height 24 and the base diameter 7 has a surface area of 305.17 units2
Formula = base * height / 2 7 * 7 = 49. 49/2 = 24.5 24.5 units squared.
1/2*(7+11)*height = 63 18*height = 126 height = 7 units of measurement
Area of any triangle is: 0.5*base*height
